arduino - MH-Z19 CO2 sensor giving diferent values using UART …

09/10/2016· I have a MH-Z19 CO2 sensor, according the data-sheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 0-5000ppm, and via PWM I should have readings between 0-2000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …

Air Quality: CO2 Sensor MH-Z14 | MySensors Forum

17/11/2014· FWIW, some weeks ago I ported the MH-Z19 code (the serial interface, by default connected to digital pins 6 and 7) to NodeManager for use in my own little gas detection node (MH-Z19 and four MQ-... sensors). The MH-Z19 code is included in the release of NodeManager, so if you are using NodeManager for your nodes, the MH-Z19 sensor should be really easy to set up and use.
