10/06/2019· Carbon Dioxide Sensor MH-Z19b - Part 1 - Hardware design. Some time ago I have purchased online carbon dioxide (CO2) sensor module MH-Z19b. It’s a cheap and very simple sensor with the UART interface allowing concentration measurement in the range up to 5000ppm. The normal level of CO2 concentration is considered about 400-1000ppm.
MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output.
The MH-Z19C module is a next-generation CO2 sensor based on the non-dispersive infrared (NDIR) principle. MH-Z19 C is the successor of the widely popular MH-Z19 B. See below for a comparison. The MH-Z19C 400~2000ppm CO2 sensor has built-in temperature compensation and communicates over UART and PWM with the host controller.
