Description

The MH-Z19C module is a next-generation CO2 sensor based on the non-dispersive infrared (NDIR) principle. MH-Z19C is the successor of the widely popular MH-Z19B. See below for a comparison.

The MH-Z19CCO2 400~2000ppm sensor has built-in temperature compensation and communicates over UART and PWM with the host controller. This particular version comes with a 7pin connector on a cable to be easily integrated with our Icon64 device.

MH-Z19C has better consistency and performance than MH-Z19B. They share same size and interface, and the MH-Z19C can directly replace the MH-Z19B.
