The Grove – Gas Sensor(MQ2) module is useful for gas leakage detection (in home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer.
- Wide detecting scope
- Stable and long life
- Fast response and High sensitivity
- Gas leakage detection.
This is a Analog output sensor. This needs to be connected to any one Analog socket in Base Shield. The examples used in this tutorial makes uses of A0 analog pin. Connect this module to the A0 port of Base Shield.
It is possible to connect the Grove module to Arduino directly by using jumper wires by using the connection as shown in the below table:
The output voltage from the Gas sensor increases when the concentration of gas increases. Sensitivity can be adjusted by varying the potentiometer.
