Methane CNG Gas Sensor MQ-4

Description: This is 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.

This sensor has a high sensitivity and fast response time. The sensor's output is an analog 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.

The sensor can be simply connected using Gas Sensor Breakout Board.
