Human beings and all the living organisms in this world needs fresh and healthy air to survive. But now-a-days air pollution has been a major problem in the global environment. Due to the toxic gases ...

We designed the Automatic LPG Gas Leakage Detection System using Arduino. This system helps in detecting lpg gas leakage and alert.

HI, thank you for publishing this project. Can you please give a reference for the gas sensor you used? Or a link where to buy one? Or both? :-) Is it an MQ-2?

Arduino Nano MQ-2 is the most common Metal Oxide Semiconductor (MOS) type gas sensor. It is very sensitive to smoke and other flammable gases like LPG, Butane, Propane, Methane, Alcohol, Hydrogen, and ...
