CO2 MH-Z19C sensor for LanControler 3.8

The MH-Z19C sensor uses the principle of insolvenous infrared (NDIR) to detect CO2 concentration in the air. The sensor is characterized by good selectivity and works regardless of oxygen. It has built -in temperature compensation and sends data through UART or PWM output. The sensor calibrates every 24 hours (it can be turned on and off with the command), but the zero point calibration can also be activated manually.
Compared to the previous model (MH-Z19B), the heating time has been shortened from 3 to 1 minute and energy consumption has been optimized.
