MQ-7 Carbon Monoxide Gas Sensor

Description:

The MQ-7 carbon monoxide gas sensor module senses concentrations of CO in the air. The MQ-7 carbon monoxide gas sensor module can detect CO gas concentrations from 20 to 2000ppm.

A highly sensitive sensor with a quick response time that uses analog resistance as an output and is extremely easy to connect with the use of Arduino as well as other devices.

The MQ-7 carbon monoxide gas sensor modules sensitivity is manually adjusted and not calibrated.
