While LPG is an essential need of every household, its leakage could lead to a disaster. To alert on LPG leakage and prevent any mishappening there are various products to detect the leakage. Here we have developed an Arduino based LPG gas detector alarm. If gas leakage occurs, this system detects it and makes an alert by buzzing the buzzer attached with the circuit. This system is easy to build and anyone who have some knowledge of electronics and programming, can build it.
Here in this project LPG gas sensor module is used to detect LPG gas. When gas leakage occurs, it gives a HIGH pulse on its DO pin and arduino continuously reads its DO pin. When Arduino gets a HIGH pulse from LGP gas module it shows “LPG gas Leakage Alert” message on android phone or 16*2 LCD and activates buzzer which beeps again and again until the gas detector module does’nt sense the gas in environment. When LPG gas detector gives LOW pulse to arduino, then message shows “No LPG gas Leakage”.
