Air Quality: CO2 Sensor MHZ14 | MySensors Forum

Nov 17, 2014· FWIW, some weeks ago I ported the MHZ19 code (the serial interface, by default connected to digital pins 6 and 7) to NodeManager for use in my own little gas detection node (MHZ19 and four MQ... sensors). The MHZ19 code is included in the release of NodeManager, so if you are using NodeManager for your nodes, the MHZ19 sensor should be ...

Gravity: Analog CO2 Gas Sensor | Arduino Official Store

This is the first CO2 sensor compatible with Arduino. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON/OFF) will be released.
