This is the MH-Z19 Infrared CO₂ Sensor Module for CO₂ monitors. The MH-Z19 NDIR infrared gas module is a common type of small-sized sensor using the non-dispersive infrared (NDIR) principle to detect the existence of CO₂ in the air, with good selectivity, non-oxygen dependence, and long life.
The built-in temperature sensor can do temperature compensation; it has digital output and analog voltage output. It is developed by the tight integration of mature infrared-absorbing gas detection technology, precision optical circuit design, and superior circuit design.
The MH-Z19 NDIR infrared gas module is widely used in HVAC refrigeration and indoor air quality monitoring.
