Intelligent LP Gas Leakage Detector

LP Gas Leakage can be very dangerous because it increases the risk of Fire or deadly Explosion. In modern homes and buildings are fully equipped with fully automatic security systems that stop the supply of the gas as soon a leakage is detected.

But unfortunately those detectors are pretty much expensive. That’s why I build this simple and very sensitive LP Gas Detector. This detector will turn on the Relay, buzzer and Red LED as soon as a leakage takes place. Detector will warn you via a Red LED and a Buzzer that sounds as long as the leakage occurs, stopping only when the problem disappears. This detector is calibrated to detect gas up to 10% of the L.E.L (Low Explosion Limit). Small gas quantities coming out from the left open cookers for some MINUTES do not cause the gas detector alarm signaling even if it is clearly nose perceptible; in fact the quantity of gas presents in the environment can be under the alarm threshold.
