MQ 4 module is a very easy to use low cost semiconductor Gas sensor Module with analog and digital output. This module uses MQ 4 Methane gas sensor as a gas sensing element. It requires no external components just plug in Vcc & ground pins and you are ready to go.For Digital output the threshold value can be easily set by an on-board potentiometer. Using this module you can easily interface MQ4 Methane (CNG) gas Sensor to any Microcontroller, Arduino or even Raspberry Pi. Since the MQ 4 Methane Gas Sensor module is sensitive to Methane, it is also small sensitivity to alcohol & smoke.
