MH-Z19 Infrared CO2 Sensor Module for CO2 monitor

The CO2 monitor’s MH-Z19 Infrared Sensor Module is this one. With strong selectivity, non-oxygen dependence, and a long lifespan, the MH-Z19 NDIR infrared gas module is a common type of tiny sensor that uses the non-dispersive infrared (NDIR) principle to detect the presence of CO 2 in the air.

The integrated temperature sensor features an analog voltage output and a digital output, allowing it to compensate for temperature changes. It is created through a close combination of excellent circuit design, precise optical circuit design, and established infrared absorbing gas detection technology. The HVAC refrigeration and interior air quality monitoring systems both make extensive use of the MH-Z19 NDIR infrared gas module.
