I want to make a GAS SENSOR with Spark Core and MQ-2. When flammable gas in the premises it generate Alarm and send Notification PushingBox.
Sounds like a good project I was planning on something similar for detecting carbon monoxide just need the time to put it together
I have a really simple example project that uses one of these sensors and a core, I’ll try to post it when i get a chance
Connecting them is easy, calibrating them for best accuracy is a bit trickier.
