MH-Z19C-PH Infrared CO2 sensor, MH-Z19C, pin header RM 2.54

The MH-Z19C Infrared Gas Module is a small sensor that uses the non-dispersive infrared (NDIR) principle to detect the concentration of CO2 in air. The sensor features good selectivity and operates independently of oxygen. It has a built-in temperature compensation and outputs the data via a UART or PWM output. Compared to the previous model (MH-Z19B), the preheating time has been reduced from 3 to 1 minute and the power consumption has been optimized. The sensor calibrates itself every 24 hours (can be switched on and off by command), but a zero point calibration can also be activated manually.
