ABSTRACT: This fire alarm system project is used to detect a fire and generate an alarm to alert the people in the buildings, offices and where it is installed. This project uses a BC177 transistor to sense the heat produced due to the fire. A preset level can...
ABSTRACT: The digital stop watch with an LCD display is used to measure the time required for a particular event. This watch is quite different compared with other clocks in many ways This watch needs much more accuracy than the normal clocks. This project uses an...
ABSTRACT: Automatic Street Light Control System is a simple yet powerful concept, which uses transistor as a switch. By using this system manual works are 100% removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes....
ABSTRACT: Solar energy is converted into electrical energy by photo-voltaic cells. This energy is stored in batteries during day time to be utilized during night time. This project deals with a controlled charging mechanism that avoids over charge, deep discharge and...
ABSTRACT: In this project the voltage-fed high-frequency series resonant inverter with a lossless snubber capacitor and an auxiliary capacitor switched cell is used for induction heating applications. By the use of capacitor clamped half-bridge high frequency...
ABSTRACT: The project aims at controlling the AC power by using the concept of firing angle control of thyristors. One can enter the required percentage of power supply through a keypad. The input is provided to a microcontroller of 8051 family that initiate the...
