Problem with UART reading (MH-Z19B sensor) - MicroPython …

23/05/2021· Recently I connected successfully a MH-Z19B sensor to my PICO via UART. The CO2 level as result will then be displayed on a SSD1306 screen. The codes work fine. So I decided to save the it as to have it running automatically once it is connected to external power source (USB). Then the strange thing happened. I got no sensor reading. The led in MH-Z19B blinks, no value can be …

Experiences with an MH-Z19 CO2 sensor | Erland Lewin ...

My experiences with the MH-Z19 NDIR CO2 sensor Warning: I just destroyed my MH-Z19 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 ...
