MICROCONTROLLER: It takes input and after processing it gives required output.

SMOKE SENSOR: smoke sensor is mounted at the place air is passes out. This sensor senses the smoke present in the air and send signal to the microntroller…

P RETROLLIUM SENSOR: In petrollium sensor, MQ6 module is used and send its analog value to ADC to convert it into digital value in microcontroller…

TRANSFO RMER: Here step-down transformer is used to power electronics circuits.

GSM MODULE: GSM module is use to communicate with electricity distribution department. It will send SMS to the department whenever there will be any problem….

TEMPER ATURE SENSOR BLOCK: The temperature sensed by using LM 35. The output voltage of LM 35 varies in liner proportion with the temperature. The sensitivity of LM 35 is 10 mV/0C. For 1 0C output of LM35 is 10 mV. For 10 0C output of LM35 is 100 mV.
