Description

MQ-7 Carbon Monoxide Gas Sensor Module detects the presence of Carbon Monoxide (CO) Gas. It is suitable for sensing CO concentrations in the air.
This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The sensor’s conductivity gets higher along with the CO gas concentration rising. The sensitivity of the sensor can be adjustable by a potentiometer.
It is mainly used for CO, gas detection in family, factory or underground operation
