Products Description

MH-711A carbon dioxide gas sensor is a general-purpose intelligent infrared gas sensor, which uses non-dispersive infrared (NDIR) principle to detect carbon dioxide in the air. It has good selectivity, no oxygen dependence, stable performance and long life. Built-in temperature compensation. The sensor is a compact high performance sensor made by combining mature infrared gas detection technology with micro machining and sophisticated circuit design.

 

Features: The value ranges from 0 to 5% Vol High sensitivity, high resolution, low power consumption, fast response time UART, analog voltage and other output modes are provided Resistance to water vapor interference, no poisoning

 

Applications:

 

Can be widely used in industrial field instrumentation, industrial process and safety monitoring
