MH-Z19 Infrared CO2 Gas Sensor Module for CO2 monitor

MH-Z19 Infrared CO2 Gas Sensor Module for CO2 monitor is MH-Z19B Infrared CO2 Sensor Module for CO2 monitor. The MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of Carbon Dioxide 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-Z19B or MH-Z19C NDIR infrared gas module is widely used in the HVAC, building ventilation system and indoor air quality monitoring system.
