Electrical and Electronics Projects for Diploma Students

The list of electrical projects for diploma students includes the following.

Automatic Elevator by Overload Alert

This project is used to stop the elevator from the damage that occurs due to heavy load. This project uses IR sensors for detecting the persons who enter into the elevator & increases the counter automatically. This increased count can be displayed on the seven segment display for indicating the people within the elevator at a fixed time.

This project uses a buzzer to generate the ring once the number of people within the elevator increases the limit. This buzzer will stop automatically once the number of people within the elevator exists so that the counter number will be decreased.

Automatic Door Opening Based on Motion

This project implements a system for opening the door automatically depending on the motion of humans. This project is used in offices, hotels, shopping malls to open the door automatically by sensing a person near the door. This can be achieved by using PIR sensors by detecting infrared energy from the live body. This signal can be processed & the door is opened as well as closed depending on this data.

When a person reaches the range of the sensor, then it detects the person & sends a signal to open the door and it closes the door in a precise time delay if there is no motion at the door. Further, this project can be improved by including a counter device so that number of persons can be tracked inside the capacity.

TV Remote based Controlling of Dish Position

This project is used to position a dish at an exact angle to get the maximum signal through a TV remote. This project can be built with an 8051 family microcontroller by interfacing with two motors. So that microcontrollers can generate commands to control the directions of dish movements in vertical as well as horizontal.

By using the IR remote, the transmission of coded signals can be done from transmitter to receiver. The receiver decodes the signal & transmits it to the microcontroller to start the motors for providing the movements using the motor driver IC. The code used by the TV remote is RC5 code and this code can be recognized through a microcontroller for generating suitable signals.

Detection of Overheat Machine by Alert

This project detects the temperature of a device when it gets overheated. This project is used where machines get overheated like industries and factories. The sensor used in this system is a digital temperature sensor for detecting temperature & transmits the data toward the microcontroller.

Further, this microcontroller processes data & transmits the temperature to display on the LCD screen. The temperature can be controlled through four pushbuttons and the power supply can be provided to this system by using a 12V transformer. If the system increases the temperature to a set limit then an alarm can be generated.

Vehicle Detection through Street Lights

This project implements a system to control the street light based on vehicle detection. By using this project, the energy is conserved through detecting the vehicle movement on highways to turn ON the block of a street light in front of it & turns off the switching lights simultaneously.

Telephone Router

This telephone router can be implemented using a microprocessor and it is capable of routing telephone calls in different directions through the switches. This router is extremely useful where the density of the telephone is very less. This router plays a key role in routing incoming calls by placing them at different locations from master to slave. Further, this device does not permit the locations of the slave to build an outgoing card.

Cellular Voting Machine based on Microcontroller

Nowadays, the usage of electronic devices is increasing. Similarly, devices like EVMs are used for voting purposes. Here, the proposed system is implemented namely a cellular voting machine using a microcontroller. This system includes two units namely a master & voting.

The voting unit can be arranged anywhere & the master unit can be arranged within a control room. This unit mainly includes a DTMF decoder that produces a DTMF tone & can be sent to the master unit using the FM transmitter.

The master unit includes a DTMF decoder, FM receiver, Display unit & Microcontroller. The DTMF tone from the voting unit can be obtained through the receiver and is decoded and specific functions are carried out by microcontroller and then it is displayed.

Barcode Decoder using Microcontroller

The barcode decoder using a microcontroller can be used to decode code 39. This was the primary barcode symbology for encoding alphanumeric data strings. This code is used in many industries for their requirements of labels. The decoders like HP barcoders are used in badges as well as barcoded cards to give an outstanding scanning performance.

Whenever a barcoded-based card is swiped then the slot reader provides a stream of pulses through changing widths. The count equivalent to these pulse widths is stored within the RAM. Later, the Intel Corporation implemented it to evaluate the pulse widths which are stored using the character set & the output of the decoded can be demonstrated on the LCD.

Smooth Start of a Single-Phase Induction Motor

This project implements a single-phase induction motor for a smooth start. This project main goal is to defend this motor using a low voltage supply at begin & after that to increase the voltage to operate the motor very smoothly. Because of the interrupt within the voltage supply at begin, the induction motor may get damage & in some cases, the motor windings can also be damaged. Therefore, this project mainly targets to provide a smooth start using the SCR firing angle control concept.

Electronics Projects

In addition to the electrical projects, the following is a list of electronics projects for diploma students, particularly for the sake of those students who have an interest in electronics. We are providing project ideas with a variety of project topics that fulfills their necessities. This article consists of a diploma based projects list

Gas and Fire Accident Avoiding System

This project implements a system for avoiding gas as well as fire accidents by detecting these leakages. The proposed system includes both the sensors like fire and gas for the purpose of detection. Once this system detects the leakage of gas, then it turns off the gas supply to evade more gas leakage and immediately gives an alert to the concerned person via an SMS through GSM. Similarly, this system uses a fire sensor to detect the fire and informs the authorized person so that he takes the required action.

The Indication of Brake Failure for Four Wheeler

This project designs a system to indicate the brake failure of an automobile. At present, this problem is faced commonly by different vehicles which cause too many accidents. To overcome this problem, the proposed system is used.

In this project, the brake condition can be checked through the microcontroller. The microcontroller used in this project is PIC16F877 otherwise 89C51. The type of brake system used in the four-wheelers is oil type or air pressure type. So this project supports both types. The connection of the braking system can be done using a pressure tank. The pressure within the tank can be detected by the pressure sensor. After that, that sensor that generates the signal can be amplified to some level of voltage level which is given to the analog to digital converter.

This converter converts the signal from analog to digital and sends it to Microcontroller. If the level of tank pressure is less, the Microcontroller triggers an alarm using the driver circuit to alert the rider. The pressure range can be displayed on an LCD display.

Biomedical Data Transmission System

Patient data acquisition, as well as transmission, is the most significant topic within medical research. So, recent enhancements within the technology are improving to provide the best solutions for medical diagnostics & therapy.

This project is used to implement a system for transmitting the biomedical data wirelessly & monitoring in real-time. The biomedical sensors used in this system are heart rate, accelerometer & skin temperature. The wireless communication is used to provide sensor data toward a PC to perform data monitoring in real-time.

Visual AC Mains Voltage Indicator

This project implements a simple as well as useful visual ac mains voltage indicator. This project is used to indicate the AC mains voltage level using three dissimilar LEDs. This project is very simple to build especially for beginners.

This system provides a visual indication for the AC mains voltage that ranges from 160v to 270 volts. This system uses a number of LEDs to specify the voltage level. The LEDs will turn off for < 160v of the input voltage.

Intelligent Automatic Three-Phase Shifter System

In an automatic phase shifter, the 3 phase power supply is R, Y, B. Once the R phase power supply in the three-phase cuts, then we can get the Y phase-only & B phase can get at the output. So the load of the R phase cannot work.

If we use an automatic phase shifter then it will automatically adjust & we can get supply to all three phases without any power loss. If both the phases like R & Y is not coming from the electricity board then the electrical load present within the phase will not function, so by using an automatic phase shifter, we can work with all the phases. So this system is applicable for both domestic as well as commercial.

Detection of Car Over speed

At present, road accidents have been occurring due to several reasons like careless driving, over speed, not following the rules, etc. So the proposed system implements a system for detecting the speed of the car. This system detects once the car speed once it crosses the maximum limit of speed on highways.
This project includes three categories like detection of speed, acquisition of image & image processing. The speed detecting device mainly works with the Doppler effect using a microwave Doppler radar sensor.

The car speed can be estimated using the preset threshold & immediately camera is activated if the limit of speed increased. The image transfer and acquisition can be done using an HD camera that is connected with Raspberry pi & it is connected to the server through the internet.

The server includes the program for image processing to separate the frame of license from the picture. The number plate characters can be digitized & sends to the authority existing in the upcoming station wherever the car is heading.

Railway Level Crossing Gate Operation Remotely by Android

This project is used to implement a system for controlling the level crossing of the railway gate using an Android-based device that can be operated by the railway station master.

In general, a railway level crossing gate can be opened or closed by the station master manually. To overcome this, the proposed system is used to control the crossing motor gate through the engine driver with a phone by sending commands to a microcontroller for getting an output to drive a relay to operate the gate motor.
