Gas sensor methane MQ-4

A simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm. The MQ4 has a high sensitivity and fast response time. The sensor's output is an analog resistance. The drive circuit is very simple; Just connect it to 5V, GND, and the output to an ADC via a resistor.

Can be mounted on suitable breakout board 41004066.

Dimensions: ø19mm x 17mm (without pins)
