MQ2 Gas Sensor Project


The project detects flammable gases (LPG, butane, propane, methane, alcohol, hydrogen, etc.) via the MQ2 Gas Sensor. When a flammable gas is detected the frequency of the speaker beep increases.

The whole enchilada is controlled by a PICAXE 08M uController and some custom code. Thanks to all on the forum that have helped to educate me through your posts.
