Product Description

MH-Z14 NDIR CO2 Sensor Infrared CO2 Sensor Module Description

MH-Z14 NDIR Infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependant, long life. Built-in temperature sensor can do temperature compensation;  and it has digital output and analog voltage output. MH-490W integrate sophisticated infrared absorption gas detection technology, sophisticated light transmission design and sophisticated circuit design.


MH-Z14 NDIR CO2 Sensor Applications
HVAC refrigeration equipment, air quality monitoring equipment, fresh air system, air purification equipment, smart home, and schools.
