This circuit is a simple solution for detecting LPG gas leakage in households which causes severe physical and monetary losses if left unattended for a long time! This circuit uses a MQ-8 gas sensor which is more sensitive to LPG gas than other sensors like MQ-2. The MQ-8 gas sensor consists of a small heater coil and some chemical composition of the compound SnO2(Tin Dioxide). The heater coil remains heated always as long as the circuit is on and hence, the circuit continues to draw current even when there is no gas leakage.
