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.
