Jun 29, 2020· To change calibration modes and calibrate, go to Tasmota''s Console and use the commands: Disable Automatic Baseline Calibration: sensor15 0. Enable ABC: sensor15 1. Calibrate in clean outside air: sensor15 2. This sets the baseline to 400 ( %), which sure isn''t accurate but considered "good enough" for room air quality monitoring.

My experiences with the MHZ19 NDIR CO2 sensor Warning: I just destroyed my MHZ19 sensor when soldering, I was changing connectors with lead free solder, iron set to 380 C. I had to heat for a little while to remove the old header. Now the sensor only gives a very low value, both on PWM and serial output. Before destroying the device, I was getting strange values around 900 ppm when I should ...
