Description Methane CNG gas sensor MQ-4
This is an easy to use compressed natural gas (CNG) sensor. It is suitable for measuring natural gas concentrations (composed primarily of methane [CH4]) in air . The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm.
This sensor has high sensitivity and fast response time. The output of the sensor is an analog resistor. The driving circuit is very simple; all you need to do is supply the heating coil with 5V . In addition, add a load resistor and connect the output to an ADC.
Free breakout
This is a simple breakout board for the MQ-3, MQ-4, MQ-6, MQ-7, and MQ-8 gas sensors. The Gas Sensor Breakout allows you to use any of the oversized, oddly spaced pins on any MQ gas sensor product . This is very handy to have on hand when detecting multiple types of gases.
All you need is VCC to 5V, GND and a resistor to an ADC, that's it!
