Description

Principle Introduction:
MH-Z14A 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 dependent and long life. Built-in temperature compensation; and it has digital output, analog voltage output, and PWM output. This commons type infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, precision optical circuit design and superior circuit design.

Applications :
HVAC refrigeration equipment, air quality monitoring equipment, fresh air system, air purification equipment, smart home, and schools.

Technical parameters :
Tips:For more parameter information, please refer to the latest manual provided by salesman.
