Based on 8051 Microcontroller. Will help in detection of entry of unknown person when no one at home, fire alert, power failure, LPG gas leakage. It uses an PIR detector(Passive Infrared) which senses any IR radiation changes thus helps in detection of living beings. Also uses a LPG gas detetor which have minimum gas particles in parts per million(ppm). Thus an increase in amount of gas above the threshold of the detector will give an intterupt to the controller thus an alert(Sound Alarm/Mobile SMS) can be generated. Fire is sensed by fire detector which will give low signal to the interrupt of controller and thus an alert can be generated. For using the SMS alert, microcontroller can be connected to DB9 using MAX 232 for serial communication. A moblie which have DB9 female as data connectivity can be connected to controller and can send pre defined SMS to the particular number.
