MH-Z14A NDIR CO2 Module
1. Profile
MH-Z14A NDIR Infrared gas module is a common type, small size sensor, using non-dispersive
infrared (NDIR) principle to detect the existence of CO
2
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.
