This project is temperature control system with digital thermometer. It operates on 5 volt power supply. I have made it by using temperature sensor, magnitude comparators, relay, some digital and hybrid ICs. This circuit takes range of temperature from user and maintains the room temperature within that range, only we have to connect it with a heater or cooler and give 220 volt to the circuit. It also displays the room temperature.
