Carbon Dioxide Gas Sensor CO2 Sensor - MH-Z14A

Carbon Dioxide Gas Sensor CO2 SensorMH-Z14A Description:

The MH-Z14A carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose intelligent small sensor that uses non-dispersive infrared (NDIR) principle to detect CO2 in the air. It has good selectivity, no oxygen dependence, and long lifespan. Built-in temperature compensation; also provides digital output, analog output, and PWM output for easy use. This sensor is a high-performance sensor created by combining mature infrared absorption gas detection technology with precision optical path design and sophisticated circuit design.
