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

2021-5-23 · 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 main.py to have it running automatically once it is connected to external power source (USB). Then the strange thing happened.

mh-z19 3.0.1 on PyPI - Libraries.io

2018-11-5 · Features about calibration (both MH-Z19 & MH-Z19B), detection range change (MH-Z19B) and ABC logic on/off(MH-Z19B) are implemented at version 0.2.1 or later. I'm afraid I've just only implemented these without test due to lack necessary devices and apparatus for the test, fx: standard concentration CO2 GAS, also MH-Z19B module.
