Reads CO2, temperature and humidity fromTFA-Dostmann CO2-Monitor devices via USB.
Just connect the sensor via USB and run the example script. There is no need to set up the sensor or USB port.

npm install co2-monitor

temperature event which is triggered on an update of temperature.
The event result is an object with the following structure:
{"value":23.73,"type":"float","unit":"degree celsius","symbol":"°C"}co2 event which is triggered on an update of Co2.
The event result is an object with the following structure:
{"value":1744,"type":"int","unit":"parts per million","symbol":"ppm"}humidity event which is triggered on an update of relative humidity.
Only the AIRCO2NTROL COACH supports humidity data. The AIRCO2NTROL MINI will report humidity data with 0.
The event result is an object with the following structure:
{"value":40.75,"type":"float","unit":"relative humidity","symbol":"% rh"}data event which is triggered on updates of humidity, temperature or co2.
The event result is an object with the following structure:
{"co2": {"value":1744,"type":"int","unit":"parts per million","symbol":"ppm" },"temperature": {"value":23.73,"type":"float","unit":"degree celsius","symbol":"°C" },"humidity": {"value":40.75,"type":"float","unit":"relative humidity","symbol":"% rh" }}based on code byhenryk ploetz
