MQ SERIES 2
- This is a very easy to use low cost semiconductor Gas sensor Module with analog and digital output. This module uses MQ2 Smoke & Flammable gas sensor as a gas sensing element. It requires no external components just plug in Vcc & ground pins and you are ready to go.
- For Digital output the threshold value can be easily set by an on-board potentiometer. Using this module you can easily interface MQ2 Smoke & Combustible gas Sensor to any Micro controller, Arduino or even Raspberry Pi.
- Since this Gas Sensor module is sensitive to smoke it can be used in for fire detection. MQ2 Gas Sensor is also sensitive to flammable/combustible gasses like LPG, Propane & Hydrogen.
