This is a very
easy to use low cost semiconductor Gas sensor Module with analog and
digital output. This module uses MQ4 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 this Gas Sensor
module is sensitive to Methane it is also small sensitivity to alcohol
& smoke.
