This project monitors fire, gas leakage, movement using IR proximioty detector in home or industries. The Gas sensor is MQ2, fire is basically flame sensor module. Thse sensor outputs are given to microcontroller. The microcontroller then takes required action to turn on exhaust fans through relay driver ULN2003 IC. The relay driver circuit is basically current amplifier IC.
The system is enabled with the GSM Modem which sends SMS to the user mobile number which is stored in microcontoller memory.
