MQ-9 gas sensor has high sensitivity to LPG, Carbon Monoxide and Methane, also could be used for other combustible steam. It is a low cost sensor and is suitable for different applications. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas. When it comes to measuring the gas in ppm the analog pin has to be used, the analog pin also TTL driven and works on 5V and hence can be used with most common microcontrollers.

Sensitive material of MQ-9 gas sensor is SnO2, which has lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electro circuit, Convert change of conductivity to correspond output signal of gas concentration.
