CO2 Sensor (CO2 Sensor Module) MH-Z14 Product Description
-
The MH-Z14 NDIR infrared CO2 gas sensor small module is a universal, compact sensor that uses non-dispersive infrared (NDIR) principle to detect CO2 in the air. It features good selectivity, no oxygen dependency, and long lifespan. Built-in temperature sensor enables temperature compensation; it also provides digital output and analog voltage output for easy use. MH-Z14 combines mature infrared absorption gas detection technology with precision optical path design and sophisticated circuit design to create a universal infrared gas sensor.
