Problem with UART reading (MHZ19B sensor) MicroPython …

20210523· Recently I connected successfully a MHZ19B 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 MHZ19B blinks, no value can be …

MHZ19 MHZ19B

The English datasheet for the nonJST MHZ19B version: MHZ19B NONJST. The Chinese datasheet for the JST MHZ19B version (more detailed): MHZ19B JST. Auto Calibration: The MHZ19 is a sensor that is designed to be powered on and rarely turned off. The sensor calibrates over time (if autocalibration is on) using the lowest CO2 observed in the prior 24 hours). After 3 weeks, a value is stored ...
