This is MH-Z19 Infrared CO2 Sensor Module for CO2 monitor. The MH-Z19 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.
The built-in temperature sensor can do temperature compensation; it has digital output an 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.
MH-Z19 NDIR infrared gas module is widely used in the HVAC refrigeration and indoor air quality monitoring.
