AUTOMATIC TEMPERATURE CONTROLLED POWER SWITCHING is a technology which is based on temperature sensing IC (eg LM35), AVR microcontroller (eg. ATMEGA16) and some other important component like 16x1 LCD, relays for power switching. As everything is becoming automatic and more easy to use, Temperature Controlled Automatic Power Switching system is designed to control any power switches like light, fan, AC, heater etc… In Automatic Temperature Controlled Power Switching system, we are using LM35 IC to sense ambient temperature and this analog output from LM35 is converted to digital data using AVR A/D converter… after processing this data, corresponding output is used to show current temperature on display device like 16x2 LCD and it also used to control relays that is for ON/OFF of our device like fan, ac, heater etc… Microcontroller is programmed in such a way that it controls the switches according to the ambient temperature. When temperature is very high, then AC is power ON. At moderate temperature, fan is power ON. At room temperature, nothing is power ON. And when temperature is very low, heater is power ON
