Abstract
Energy is the most extensive need in today's world where we are wasting our energy deliberately or abstractedly. But we have to stop maltreatment to our energy. In this prospective system, a process is developed through which power will be supplied after ensuring the existence of human and gas leakage will be apprised immediately. Here, Raspberry Pi 3 and the WeMOS D1 mini is the master apparatus of this system supported by many other microcontrollers like PIR sensor, gas sensor etc. when human is not encountered by the PIR sensor for a fixed time, controlling the relay module through connection Raspberry Pi will ensure power disconnection (like: light and fans will go turn off which left turned on by the user abstractly). On the other hand, while the PIR sensor is detecting human/animal presence in a room, power(like: light, fan etc.) will be turned on through the relay module and also apprise the user about the human existence. Besides, when gas leakage is detected by Gas sensor it makes the WeMOS known about this, which transfers signal to raspberry Pi and it apprises the user immediately through GMS module. Thus, the user can restrain the unauthorized access to his home and also can rescue his home from unwanted accidents.
