MHZ19 CO2 sensor | MySensors Forum

20170323· The datasheet can be found here. There seem to be 2 version of the sensor (the manual refers to ''v2''). And you can set it to give a reading between 0 and 2000ppm or between 0 and 5000ppm. You send it a code to switch these two modes. This seems a useable code: int readCO2() {byte cmd[9] = {0xFF, 0x01, 0x86, 0x00, 0x00, 0x00, 0x00, 0x00, 0x79}; // command to ask for data char response[9 ...
