MH-Z19C (Pin) • 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.
Introduction. This device measures Carbon Dioxide (CO2) and Total Volatile Organic Compounds (TVOC) in the atmosphere. Note:The serial device mh-z19c is preferred over css811 for carbon dioxide measurement. Configuration. Adding one or more css811 to either i2c busses will allow the css811(s) to be autodetected and configured on reboot.

17-12-2020 · 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-Z19C 400~2000ppm CO2 sensor has built-in temperature compensation and communicates over UART and PWM with the host controller.
The MH-Z19C is the successor to the popular MH-Z19B and is largely compatible. This version is more stable, and in practice more accurate than the MH-Z19B. This CO2 sensor can measure the amount of carbon dioxide very accurately with the non-dispersive infrared principle (NDIR). This sensor comes w
Output signal: serial UART (TL level 3.3V). It has good selectivity, no oxygen de-pendency, and long life. High Sensitivity CO2 Sensor -- MH-Z19C NDIR infrared gas module using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent, low power consumption and longevity.
