Description

This is a simple-to-use compressed natural petrol (CNG) sensor, suitable for sensing natural petrol (composed of mostly Methane [CH4]) concentrations in the air. The MQ-4 can detect natural petrol concentrations anywhere from 200 to 10000ppm.

This sensor has a high sensitivity and fast response time. The sensor’s output is an analogue resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board below.
