Package Includes: 1 piece x MQ 7 Carbon Monoxide ( CO ) Coal Gas Sensor detector Module


This is a very easy to use low cost semiconductor Gas sensor Module with analog and digital output. This module uses 

MQ7 CO 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 MQ7 CO gas Sensor to any Microcontroller, Arduino or even Raspberry Pi.

MQ7 is a  Carbon Monoxide (CO) sensor, suitable for sensing Carbon Monoxide concentrations(PPM) in the air. MQ7 Gas sensor can measure CO concentrations ranging from 20 to 2000 ppm.
