MH-Z14A CO2 Sensor for Home, Office

 

Product Description

 

MHZ14A NDIR Infrared co2 gas sensor

 module usnondispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependant, long life.  

It has digital output, analog voltage output, and PWM output.

Application 

MH-Z14A NDIR Infrared gas module is applied 

HVAC refrigeration equipment, air quality monitoring equipment, fresh air system, air purification equipment, smart home, and schools.

 

 

Automatic Baseline Correction (ABC function)

ABC function refers to that sensor itself do zero point judgment and automatic calibration procedure intelligently after a continuous operation period. The automatic calibration cycle is every 24 hours after powered on. The zero point of automatic calibration is 400ppm. From July 2015, the default setting is with built-in automatic calibration function. To use the sensor better, the sensor must be placed in clean air for over 1 hour.

 

ABC function is suitable for office and home environment etc., but not for green house, farms, and refrigerators etc., in which it requires to shut down the automatic calibration function. Then the user should do zero detection regularly, and zero calibration by command or manually.
