Product Description:

MH-Z14A NDIR Infrared gas module is a common type, smal 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 sensor can do temperature compensation; and it has digita output and PWM output. This common type infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, Precision optica circuit design and superior circuit design.
