MQ4 Methane Gas Sensor Module, Warranty 1month, Brand ibots, Weight 100g

This represents an exceptional User-friendly design 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 is simple to 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 You will find it to be also small sensitivity to alcohol & smoke.
