The MQ2 Flammable Gas Sensor Module is useful for detecting gas leaks or presence of flammable gas. This can detect common household gases like propane or LPG. Also, this sensor features fast response times, so you can take measurements as soon as possible.
This is a simple to use sensor. Output voltage increases when flammable gas concentration increases. You can also adjust sensitivity using the sensor’s potentiometer.
