Jun 10, 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 CO2 Module 1. Profile MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output.
