LOW COST FIRE ALARM SYSTEM

  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...

INCOMING CALL INDICATION FOR MOBILE

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...

IMPLEMENTATION OF LASER MUSIC SYSTEM

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....

CHARGE AND LOAD PROTECTION IN SOLAR POWER MANAGEMENT

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...

IMPLEMENTATION OF SOLAR INVERTER

ABSTRACT: The solar energy is converted to electrical energy by photo-voltaic(PV) cells.This energy is stored in batteries during the day time in order to be utilized whenever required. This project is designed to use solar energy for household loads using Inverer....

RESONANT INVERTER FOR INDUCTION HEATING APPLICATIONS

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...
