Apr 13, 2020· MHZ19 - RevSpace - experimenting with the sensor, trying to understand the meaning of undocumented values. I tried to read the temperature and status, but it looks the MH-Z19B is not the same as MH-Z19 and returns always status zero and temperature looks maybe 10 degrees higher (so no value minus 40, but maybe value minus 50).
MH-Z19B CO. 2. Sensor. This feature is included only in The MH-Z19 sensor is manufactured by Winsen Lt., China and the measurement method used is based on the non-dispersive infrared ( NDIR) principle to detect the existence of CO 2 in the air. Key features according to the manufacturer are: * good sensitivity * non-oxygen ...
Jun 12, 2021· MH-Z14 vs. Technoline WL 1030. The results for the MH-Z19C looked very similar. Overall, I was as surprised as I was pleased with the good measurement results. However, it is also important here that the zero point calibration (more precisely the 400 ppm calibration) is carried out carefully. And this happens with poor calibration
