Let’s get started with the list of the Best 8051 Microcontroller-based Electronics Project Ideas for Electronics & Communication Engineering Students for Minor & Major Project Submissions. 8051 Microcontroller Project Ideas for B-Tech, M-Tech & Ph.D. students.
This is a mini project that uses a normal TV remote to regulate plant watering.
For sensing the IR signals transmitted by the remote, an IR sensor is connected to the control unit. This information is sent to the control unit, which turns on or off the DC water pump as needed. This project’s controller is an 8051 series microcontroller.
The 8051 controller uses the IR module to receive IR signals from the remote and then drives the motor to achieve the desired plant watering. As a result, using this tiny DIY, one may quickly water the plant by pressing a few buttons on his TV remote.
Shopping is simple, but waiting at a bill counter afterward is a laborious and time-consuming chore. The combination of a large rush and a cashier preparing the bill with a barcode scanner takes too long, resulting in long lines.
An RFID reader is used in the system, which is controlled by an 8051 microprocessor. So, anytime a shopper places a product in the trolley, the RFID module detects it and displays it on the LCD, along with the product’s price.
As the shopper adds more items, the module detects them and adjusts the price accordingly. The shopper will push the button at the end of their shopping trip, which will add all of the products, their prices, and the final amount to be paid. With the use of a master card, the shopkeeper can check the shopping at the exit.
To support appropriate plant growth, plants require both water and suitable soil (pH rich). It becomes tough to physically monitor these items regularly to maintain correct growth, and any ignorance could result in poor plant health or plant decay/death.
We present an 8051 microcontroller-based system that uses a soil moisture sensor and a ph value sensor to monitor these values continuously. By continuously monitoring for correct moisture and ph, the system microcontroller guarantees that the plant receives it.
This is also displayed on a display screen for the user to see. The device also has an alert that makes a buzz if the numbers go below a set threshold, which could be harmful to the plant’s health.
We propose a “DTMF & RF Dual Controller Based Robot,” which is an advanced type of robotic vehicle that can be controlled by a Dual Tone Multi Frequency Based Controller (DTMF), Radio Frequency (RF) based controller, and is also a stand-alone obstacle-avoidance robotic vehicle.
Its design incorporates both RF and DTMF-based controlling systems, giving it the added benefit of being able to operate across great distances. A Radio Frequency-based controlling remote can be used whenever the robot is within a 9-meter range.
When the robotic device’s location is greater than 9 meters away, a cellular network-based Dual Tone Multi-Frequency (DTMF) based controlling system can be used.
The robot is a little vehicle with motors and a sensor-based circuit that detects lines using infrared sensing and only rubs linked lines after they are set on them.
To accomplish this, the robotic system employs a microprocessor circuit from the 8051 families. To achieve the necessary cleaning, the controller examines the input sensor data and continuously drives the motors.
In addition, a wireless rf remote enables manual control of the robotic vehicle and switching as needed. As a result, the technology creates a robotic whiteboard-erasing robot that is intelligently automated.
The fundamental goal of a Motion-Based Automatic Door Opener is to open doors without the need for manual assistance.
We present this invention, which automatically opens the door when sensors detect the presence of a human person. PIR (Passive Infrared) sensors are used to power this system. When a living body emits energy, the PIR sensors detect it, and the door opens as the energy gets closer to the door and closes as the energy gets further away.
This device is capable of identifying any metallic things carried by the person and notifying him accordingly. We can improve this system by incorporating a counter device to keep track of how many persons have entered the facility.
We propose an automatic BMI calculator that does not require the user to enter any information. The user simply stands on a platform, and the system displays the person’s BMI as well as body type.
For weight sensing, the system uses load cells, and for height measuring, it uses an ultrasonic sensor. To obtain user height and weight values, the system now employs a microcontroller-based circuit.
The system calculates BMI based on the data and displays the results to the user on an LCD. On the LCD, the system now shows the calculated BMI as well as the user’s body type.
The primary goal of this study is to identify human speed. This technology uses a handheld radar gun aimed at the individual whose speed needs to be measured to record their speed.
In the event of a running race, it may be necessary to determine the competitors’ speed to make a choice or for other reasons. The suggested approach determines speed by factoring in the time it takes to go from point A to point B.
To accomplish this, an IR transmitter and receiver are put on either side of the road at predetermined spots. The control unit calculates how long it takes a human to complete a task. On an LCD screen, the human’s speed is represented.
Using fuzzy logic, this system accurately controls the speed of BLDC motors.
To accomplish this, the system employs a microprocessor from the 8051 families. We use an IR sensor to constantly monitor the motor speed here.
The sensor is used to detect the RPM of the fan motor and maintain track of its rotation. The sensor communicates with the microcontroller and provides information to it. Based on the signals provided by the sensor, the microcontroller determines motor speeds.
The microcontroller is also connected to an LCD, which shows the system’s status as well as the motor speed. To keep the fan spinning close to the intended speed, the project employs fuzzy logic to increase and decrease the PWM supply based on the fan speed measured.
By adopting an auto power factor corrector system, our project offers to reduce the energy consumption penalty for companies.
The power factor is also known as the real-to-apparent power ratio. It’s sometimes written as KW/KVA, where KW stands for active or real power and KCA refers to reactive + active or apparent power in the equation.
The power generated by inductive and magnetic loads to form a magnetic flux is referred to as reactive power, which is a non-working power. As the reactive power rises, the perceived power rises as well, lowering the power factor.
When the power factor is low, the amount of energy required to meet industry demands rises, lowering efficiency.
This system employs a robotic arm as well as a robotic vehicle to not only access a high-risk region but also to pick whatever object it desires. The system also contains a night vision camera, which allows viewing of what is captured not only during the day but also at night.
The entire system is operated via an RF remote control. The system uses push buttons to deliver commands to the receiving circuit on the car. The receiving circuit is made up of an 8051 microcontroller and a receiver that receives commands from the broadcasting circuit.
The system is initially configured to control vehicle movement. To put the system in a mode where it can control the arm. The user must first hit the push buttons to move the vehicle in the desired direction, such as forward, backward, right, or left. The user must long-press the forward and backward push buttons to generate arm movement.
Thus, this system employs a camera, robotic arm, and robotic vehicle to enter a high-risk area, as well as to pick, move, and dump an object, as well as to record and view the location where the system goes for future reference.
We run into circumstances when we need to keep an eye on restricted locations to prevent trespassing.
As a result, an ultrasonic radar project for unlawful human, animal, or object detection is being developed. The technology can monitor a limited range of regions and inform authorities via a buzzer sound.
We employ a microcontroller circuit for monitoring that is coupled to an ultrasonic sensor installed on a servo motor. A buzzer and an LCD screen are also connected to check the detection status. The radar continues to scan the area for ultrasonic sensor echo.
When an object is spotted, the detection data is processed and forwarded to authorities, along with an alert of where the thing was discovered.
The project is a power electronics control system that uses forward and reverses converters to achieve polarity DC from AC rectification.
As a result, the Dc motor may be moved in both directions and the speed can be adjusted. In a single-phase converter, a thyristor-controlled bridge is employed to achieve DC motor reverse polarity for either direction of rotation. The speed is gradually reduced by the microprocessor, which triggers each bridge SCR bank through optoisolators.
Switches with microcontroller interfaces are used to provide input to the microcontroller. When 230V AC is utilized as an input to a dual SCR Bridge with a 100Watt lamp load, DC polarity is checked across the light.
By entering wild animals’ habitats, wildlife observers can get up close and personal with them. Users can control this robot wirelessly using only their Android phones. The robot also features a wireless camera that streams video to the user’s computer.
By piloting this robotic vehicle from a safe distance, wildlife observers can get up close and personal with wild animals.
This system is made up of a microcontroller from the 8051 families that are used to process user commands. The system receives these commands over a Bluetooth modem. The data is subsequently processed by the microprocessor, which ultimately sends signals to the drive motors.
The motors are now controlled by the driver motors, which provide the necessary signal outputs to drive the vehicle movement motors. In addition, when the microcontroller gets the camera directional change signal through the Bluetooth modem, it sends it to the camera motor to obtain the required camera angle.
As a result, employing an Android cellphone to control this wildlife observation robot enables secure wildlife viewing.
The concept attempts to save energy by sensing vehicle movement on highways and turning on the street light block ahead of it while turning off the tail lights.
Sensors are required for the project, which will detect vehicle movement and turn on the lights ahead of it. The tail lights turn off automatically as soon as the car goes forward. This can be utilized to conserve a lot of energy rather than using the traditional technique of keeping the street lights on.
Another way of operation is to keep the lights on at 10% intensity until the vehicle passes by, at which point the lights ahead of it are turned on at 100% intensity and the trailing lights are turned off at 10% intensity.
PWM is a microcontroller-based method for controlling intensity. The sensors detect vehicle movement and communicate the information to an 8051 microprocessor, which sends commands to turn the lights on and off.
Our suggested project intends to create a system that identifies cars traveling at speeds beyond a set limit and quickly alerts the appropriate authorities. Because the number of road accidents has increased in recent years, a system that can detect overspeeding vehicles is required.
Current speed detection systems are portable guns carried by police officers that allow them to assess vehicle speed and manually notify authorities. This proposed system, on the other hand, does not require human interception and records car speed while also informing authorities of overspeeding detections wirelessly.
The system initially determines how long it will take a certain car to get from point A to point B. It calculates the car speed using this information. This information is gathered and wirelessly delivered by the system to the appropriate authorities at a remote location.
The system is made up of a pair of IT transmitters and receivers that work together to detect vehicles. The microprocessor is now utilized to process this information and determine how long it will take the vehicle to go from point A to point B.
It now estimates vehicle speed and shows it on an LCD based on the current time. This data is also sent wirelessly by the system. If an Overspeed vehicle is identified, a buzzer alarm sounds.
The suggested project is a wireless communication system that uses RF transmission to keep track of a remote patient’s body temperature and display it to the doctor.
As a result, the system uses a digital temperature sensor to read the temperature of faraway patients and delivers it to a microcontroller. The microcontroller then encrypts the data, displays it on the LCD, and delivers it to the receiver via RF over the air using an RF module.
The data is decoded by the receiver and sent to a second microcontroller, which displays it on an LCD screen. As a result, the doctor may keep a constant eye on the patient’s readings displayed on the LCD via a wireless receiver.
For improved visibility, the project is designed to display the phone number dialed on a seven-segment display.
The project employs the DTMF principle, in which each telephone button generates a distinct frequency when pressed, which is received and processed by a DTMF decoder.
These decoded signals are then passed through buffer circuits to a microcontroller (of the 8051 families) for processing. The microcontroller’s output is sent to a seven-segment display that is linked in parallel.
The seven-segment display is set to high multiplexing mode, which means that the digits are displayed instantly as soon as they are dialed. To receive data, the DTMF receiver is linked to the earphone jack.
A hovercraft is a non-wheeled vehicle with high-powered fans and an aerodynamic design that allows it to easily hover over land and water.
To provide needed functionality, we propose an advanced hovercraft that uses high rpm motors interfaced with an Avr family microcontroller. The motor beneath the hovercraft rotates at a very high RPM, allowing it to provide enough force to have it hover on the surface while minimizing friction below it.
The hovercraft is then propelled forward using the engine propeller situated behind it. We’ll also need to employ a servo motor attached to the hovercraft rudder, which bends the air at precise angles to help the hovercraft go in the right direction.
The system works together to hover while constantly controlling the servo and propeller motor to push the hovercraft in the desired direction. We now utilize an android application to control the hovercraft. The hovercraft circuit receives movement commands from the android application.
To receive and process these commands, the circuit includes a Bluetooth receiver. The microcontroller processes the commands received by the receiver and then operates all three motors as desired by the user.
This compact device uses a tiny three-volt solar cell to charge a six-volt NiCad battery set, which may then be used to charge a variety of cell phones and other useful devices.
The circuit uses current pulses to “hunt” for power from the solar battery by keeping it loaded close to 1.5 volts (the maximum energy transferring value) and trickle charges the inner battery.
The simple circuit is not the most efficient, but it manages a respectable 70% efficiency at 100 mA from the battery and 30% efficiency when the battery is only producing 25 very good mA without causing any further problems or requiring the use of other foreign or unwanted elements.
Our project’s main goal is to build and present a useful electronic notepad. The notepad will have a touch screen and a storage memory to save the data that is written.
This notepad will allow you to send data to a computer whenever you need it. This data is transferred using software that understands the data and shows it on the screen. The notepad has a high sample rate and accuracy, which will aid in displaying the exact drawing you produced.
The circuit of the notepad is interfaced with a microcontroller and an SD card. The microcontroller uses a serial connection to deliver data to the computer’s SD card when you tell it to.
This project is used to give an alert to the car driver while parking the car or while driving in the reverse direction if there is any wall or obstacle that occurs.
The design of this project can be done with the help of an 8051 controller. This project is mainly used to deactivate the power supply by entering a secret word.
This project is used to design a simple & easy five-channel-based remote control system, used to drive 5 different loads. This project uses the IR communication principle.
The project’s goal is to construct a post office stamp value calculator system. In post offices, letter weights are calculated in grams so that an appropriate postal charge can be applied.
As a result, a high-precision weighing instrument is required to determine the exact weight and display it. The technique can be easily implemented using electronic weighing equipment to complete this operation.
The system not only shows the weight of the letter but also the stamp value that will be applied to it. The system consists of a spring-loaded weight sensor and an 8051 series microcontroller.
The device calculates the exact weight of the package and displays it together with the postal charge that will be imposed.
The project’s goal is to use an ultrasonic transducer to measure the distance between any two objects in inaccessible places such as high temperature and pressure zones, where standard approaches are ineffective.
The ultrasonic module is controlled by a microcontroller from the 8051 series. A transmitter and a receiver make up an ultrasonic module. The sound waves are transmitted by the module to the object, and the waves are reflected by the transducer.
The total time taken from sending the waves to receiving them about the velocity of sound is used to compute the distance. The programmed microcontroller does the calculation and shows the results on the LCD screen.
The goal of the project is to use a loop-based control technique to control the speed of a BLDC motor.
To control the speed, the project employs the PWM principle. The BLDC motor is kept on closed-loop feedback, and a shaft-mounted IR reflection setup provides RPM reference to the microcontroller.
The IR sensor connected to the microcontroller measures the speed, which is displayed on the LCD. The desired speed in percentage is provided to the microcontroller via the keypad, which generates pulse width to adjust the DC power automatically.
The optoisolator and MOSFET are then turned on by the microcontroller to operate the BLDC motor at the desired speed.
A transmitter app is part of the system. This app runs on an Android phone and allows the user to send commands based on their input.
The transmitter transmits movement commands to the robot based on these commands. The transmitter is an Android phone that the user can use to send commands to the robot.
The robot is made up of two cleaning pads and a water sprayer for thorough cleaning. For the cleaning phase, the robot includes two motorized rotating cleaning scrubs. After receiving the android’s movement directions.
When using a Bluetooth receiver to receive movement orders from an Android device. When the commands are received, the microcontroller decodes them and then activates the motors to accomplish the desired motion.
This Long Range Spy Robot with Obstruction Detection technology allows you to not only control the robot’s motions but also to halt it when it comes across an obstacle.
The system accomplishes this through the use of DTMF technology, which allows data commands to be sent over the phone. To control the robot, the user only needs to make a phone call to the system’s mobile phone.
This system uses a microcontroller from the 8051 families that are connected to an ultrasonic obstacle detector, a spy camera, and a battery. The ultrasonic obstacle detector aids in the detection of any obstacles in the robot’s path.
When the robot discovers an obstruction, it comes to a complete halt and waits for user orders. The user must make a phone call to the robot’s phone to run the device. The receiver phone must receive the call to get the data commands required for robot movement.
The robot will move forward, backward, left, or right depending on the data commands. The system employs a night vision spy camera, which allows the user to examine the region captured by the spy camera that will be put on this robot.
The region covered by this wireless camera can be viewed not only during the day but also at night. This spy camera’s whole capture area can be viewed on a computer.
A Propeller-based display is a display that works on the phenomenon of persistence of vision. Persistence of vision is what makes discrete images incident on a human eye and changing at a rate of almost one-sixteenth of a second appears to be an image collection of all the individual images.
This concept has been used in this project to demonstrate a live clock that displays Time in the format of HH:MM: SS. For making it a more robust system, the system has instantaneous time change capability as per the user’s input to give correct time information as per the user’s demands.
Digital Propeller Clock with Android Override project is built around the Atmega family microcontroller. The system has a high RPM motor which makes the system rotate.
The LEDs arranged in a row across the PCB turn ON and OFF at specific intervals when the system rotates to produce an image of a character in the eye of the human watching it. This makes the observer believe that he/she is watching a digital clock that has a few LEDs lit for each of the digits displayed in the clock.
To make the information given by the system to be in synchronous with what the user wants the system also has a Bluetooth interface. By using the Android Override via Bluetooth on the Android cell phone of the user, the user can update the time that the Propeller Clock is displaying.
This system can prove to be very useful in various scenarios where the user wants a propeller-based display that consumes less space and less electricity, and is also in synchronicity with the user’s choice of time.
A standard television remote sends data in a coded fashion. This information is obtained by an infrared sensor, which is then connected to an 8051 microcontroller. The data signal is then sent from the microcontroller to the computer’s com port using a level shifter IC.
This IR code is usually just an RC5 code. The remote input command on the computer is read using pc remote reader software. It recognizes the input command and executes the intended action. The numbers on the tv remote keypad are used to move the cursor Right-Left-Up-and-Down.
The remote can also be used to do mouse left/right clicks. Other technologies that can give a wider range of communication can be used to improve this system in the future.
The project involves a robotic vehicle that is programmed to follow a predetermined path.
To maintain track of the journey, this device employs an 8051 microprocessor, as well as an IR transmitter and photo sensor pair. The line follower robot is used in a variety of workshops, industries, and other locations where unmanned vehicles must follow a predetermined path without requiring tracks.
This line-following robotic car was created using our technique. Each one has a photo sensor pair consisting of a photodiode and an infrared transmitter. Signaling its microcontroller, it assists the vehicle in finding its course along the line.
Two DC motors are employed, each of which is connected to the microcontroller through a motor driver IC. Interfacing ultrasonic sensors will allow the car to detect any obstructions in its route, which will improve the system even further.
This innovative project, Fire Fighter Robotic Vehicle with Night Vision Camera, allows a user to remotely manage a firefighter robot equipped with a water tank and rifle to put out flames.
For this, the system employs an Rf remote for remote control, as well as a microcontroller circuit based on rf received for controlling the robotic vehicle and water pump.
RF signals are received by the receiver circuit using RF-based remote transfer user commands. The data commands are now decoded by the receiver circuit. It then sends the information to the microcontroller.
The microprocessor now processes these commands and sends them to the vehicle motors, which ultimately drive the car in the desired direction. It also controls the water pump motor and the pump direction motor, spraying water according to the user’s commands.
By standing at a safe distance, the user may control the robot and extinguish the fire. A wireless night vision camera is installed on top of this robot’s body.
This night vision camera aids in directing the robot’s body in the desired direction. This is because whatever region is taken by this wireless camera can be seen on a computer for reference.
The robot may be controlled by the remote within an 8-meter range. With the help of the water tank linked to the robot body, this technology enables extinguishing fire from a safe distance.
The goal of the project is to design a three-phase solid-state relay system.
It is made up of three single-phase units, each of which is individually controlled by a power TRIAC and a zero-voltage switching RC snubber network. Opto-isolators are required for each phase to receive switching signals from the 8051 series microcontroller.
Loads are connected in series and driven by optoisolators using a set of TRIACs. After a zero voltage pulse, the microcontroller creates pulses as output and ensures that the load is switched on at the zero cross of the supply waveform.
The zero crossing feature of the TRIAC driver (an optoisolator) ensures low noise generation by preventing rapid inrush of current inductive and resistive loads. Two push buttons are employed to generate output pulses from the microcontroller that do not correspond with the waveform’s zero voltage supply.
To ensure that the load switches at zero voltage, a DSO or a CRO can be used to view the supplied voltage waveform to the load.
The goal of the proposed project is to use a mobile phone to drive a car.
The project necessitates the use of two mobile phones, one to control the robot and the other to deliver DTMF signals to the robot vehicle. The commands are received by a DTMF decoder connected to an 8051 microcontroller, which then controls the vehicle movement with the help of a motor driver.
Thus, with the motor driver IC, two DC motors enable vehicle movement based on commands supplied by the phone. The power source is a battery.
We see a variety of devices in our daily lives that display text, images, and graphics. LCDs are one of the most used display devices in electronics, and they’re employed in almost all projects that display data.
LCDs come in a variety of shapes and sizes, and they’re employed in a variety of electronic projects.
The DS1307 serial real-time clock (RTC) is a low-power clock/calendar with complete binary-coded decimal (BCD) and 56 bytes of NV SRAM. The I2C protocol is used by this chip.
The clock/calendar displays information such as seconds, minutes, hours, days, dates, months, and years. For months with fewer than 31 days, the end-of-the-month date is automatically modified, including leap year corrections.
The clock has an AM/PM indicator and works in either a 24-hour or 12-hour mode. The DS1307 includes a built-in power-sense circuit that detects power outages and switches to the backup source automatically.
While the part is running on the backup supply, the timekeeping operation continues. The DS1307 chip can run indefinitely for up to ten years.
We will create an RFID and keypad-based security system in this project.
The 8051 microcontrollers are used to implement this project. RFID (Radio Frequency Identification and Detection) technology is widely utilized in schools, colleges, offices, and stations to automatically verify people with genuine RFID tags for a variety of functions.
To protect the system, we will check the RFID tag, as well as a password connected with the tag. The entire security system can be divided into several pieces: the reader, keypad, control, driver, and display portions.
GSM and GPS-based car tracking and location systems will enable effectively, real-time vehicle tracking, mapping, and reporting increasing the value of the service given.
A GPS-based vehicle tracking system will tell you where your car is and where it’s been, as well as how long it’s been there. Global Positioning Satellite (GPS) data is used to calculate the system’s geographic position and time.
The system consists of an “OnBoard Module” that is installed in the tracked vehicle and a “Base Station” that monitors data from all of the vehicles. A GPs receiver and a GSM modem are included in the On-Board module.
We understand the value of notice boards in public places such as train stations, bus terminals, and airports. Changing notices daily, however, is a demanding task. This article will show you how to create a GSM-based Wireless Electronic Notice Board.
The data we sent from the phone is shown on the LCD by the project. There are various wireless communication technologies available, such as Bluetooth, RF Connection, ZigBee, and others, but GSM Technology enables long-range, dependable, and secure communication.
As the name implies, the Wireless Electronic Notice Board utilizing the GSM project is based on GSM Technology, as mobile phones (which communicate via GSM Technology) have become increasingly common, inexpensive, and simple to use.
An embedded system is a computing device that is dedicated to a single task. Air conditioners, VCD players, DVD players, printers, fax machines, and mobile phones are all instances of embedded systems.
Each of these devices will be equipped with a processor and specialized hardware. Embedded systems are designed to do a single purpose and cannot be programmed to perform several tasks. Embedded systems have a certain amount of resources, especially memory. They don’t usually have supplementary storage devices like CDROMs or floppy discs.
Embedded systems are required to meet certain deadlines. A specified task must be done within a certain amount of time. Deadlines are strict in some embedded systems, known as real-time systems.
Power is a constraint for embedded systems. Because many embedded devices are powered by a battery, power consumption must be kept to a minimum. Some embedded systems must function in harsh environments, such as extremely high temperatures and humidity.
