2014-11-17· 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.
2021-03-27· CO2 levels can have many negative effects on your body, here is a list of the values that one should be aware of and their effect: 250-400ppm -> Normal background concentration in outdoor ambient air. 400-1, 000ppm -> Concentrations typical of occupied indoor spaces with good air exchange. 1, 000-2, 000ppm -> Complaints of drowsiness and poor ...
