May 23, 2021· 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.

Mar 23, 2017· I have to mention I''m using the MHZ19B, and powering it with 5V, as opposed to the of the arduino. I also tried with the mhz19_uart lib, but didn''t go further with it as the samples where not working out of the box with the z19B. Will probably give it another try, though...
Jun 30, 2017· Introduction: In this article we will do a simple functional test of the MHZ19 CO 2 sensor by connecting it to a raspberry pi 3 UART and run a simple datalogger python program which prints results to the screen and stores results in a csv formatted file. The file can later be imported to matlab or excel for further analysis or just plot a graph of the collected data.
