Gravity: Analog Gas Sensor (MQ2) For Arduino

This is a generic Arduino gas sensor. It has MQ2 probe which is able to detect LPG, i-butane, propane, methane ,alcohol, Hydrogen, smoke.  It can be used in gas leakage detecting device in consumer and industry markets. It has a high sensitivity and fast response time.

To ease the difficulty of using this sensor, a Gravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match for this senor connecting to your Arduino. As this sensor can work at 3.3V which makes it compatible with Raspberry Pi, intel edison, joule and curie. 

1. Power supply needs: 5V

2. Interface type: Analog

3. Wide detecting scope

4. Fast response and High sensitivity

5. Simple drive circuit

6. Stable and long life

7. Size:36.4x26.6mm (1.4x1'')
