MQ2 Smoke Detector Shield for Arduino

via Jaycar
Detects the concentration of flammable gas and smoke in the air and outputs its reading as an analog voltage. The sensor can measure conentrations of flammable gas of 300 to 10,000 ppm. With fast response and adjustable sensitivity , it is useful in quick detection of leaking gas including LPG, I-butane, methane, alcohol, hydrogen and smoke.
