Vehicle Movement Sensing Led Street Light With Off-Peak Hour Time Dimming

The main intention of this project is designed to detect a vehicle movement on road to switch on only a block of street lights that are in front of the vehicle, and automatically switch off the glowing lights when the vehicle passes away from the lights.

 This will help to save more electrical energy. The IR Sensors are placed on both sides of the traveling way, that are used to sense the object’s movement and send the logic commands to an 8051 microcontroller to switch on or off the LEDs for a specific distance. Hence, this way of dynamically switching on and of the street lights

Precise Detection of Distance in Underground Cable Fault

The main aim of this project is to determine the distance of the underground cable fault from the base station in kilometers.  It is very difficult to repair of underground cables in case of any faults occurs. This proposed system is used to find the exact location of the fault is possible.

 This project, assembled with a set of resistors representing cable length in km and fault creation is made by a set of switches at every known km to cross-check the accuracy. If the fault occurs at a certain distance of a particular phase is displayed on the LCD display. The whole circuit controlled by the 8051 microcontrollers.

Detecting the Power Grid Synchronization Failure System

This project is to detect the failure of power grid synchronization while sensing the frequency and voltage which are not in an acceptable range, and then preventing the power supply to the distribution system. The microcontroller continuously monitors the over/under voltages and frequency using a set of comparators.

Since the main supply frequency cannot be altered, so this project uses a 555 timer for varying the frequency, whereas a standard variac (autotransformer) is used to vary the input voltage to test the working of the project.

Soil Moisture Sensed Auto Irrigation System

The goal of this project is to develop an automatic irrigation system that switches the pump motor on/off on sensing the moisture content of the soil. The improvement of using this method is to reduce human intervention and to ensure proper irrigation.

This project uses an 8051 series microcontroller which is programmed to receive an input signal of varying moisture conditions of the soil through the sensing arrangement. Once the controller receives this signal, it generates an output that drives a relay for operating the water pump. This is achieved by using an op-amp as a comparator.

These frequencies are decoded by the DTMF decoder IC at the receiving end, which is fed to the 8051 microcontrollers.

Time Programmed Sun Tracking Solar Panel

This project employs a solar panel mounted to a time-programmed stepper motor to track the sun so that maximum sunlight is made incident upon the panel at any given time of the day. This is best compared to the light-sensing method that may not be accurate always – for example, during cloudy days.

The microcontroller used in this project is from the 8051 families. The Stepper motor is driven by an interfacing IC as the controller is not capable of handling the power requirements of the stepper motor. This particular project is provided with a dummy solar panel, which can be used for demonstration purposes only.

DC Motor with PWM Speed Control in All Four Quadrants using Microcontroller

The main concept of this project is designed to develop a four-quadrant-speed-control system for a DC motor with PWM. The motor is operated in four quadrants they are clockwise, counterclockwise, forward brake, and reverse brake. It is very useful for industries wherein motors are used as per the requirement.

The microcontroller used in this project is from the 8051 families. Few push-buttons interfaced with the microcontroller are provided for the operation of the motor and for the input signal to the motor and in turn, control the speed of the motor through the motor driver IC.

AC Power Transfer Wirelessly by HF

The main concept of this project is to transfer the electrical energy wirelessly from a power source for electrical loads. In this project using a high-frequency resonating air-core transformer to develop the frequency from 50Hz to 40 kHz for transferring power over a distance of 3cm.

The wireless power transfer is developing a high-frequency supply from 230v 50Hz AC to 12v 25-40 kHz AC supply, a high-frequency transformer is used. The output is fed to a tuned coil forming as primary of an air-core transformer. The secondary coil is received to run the load.
