Rationale
PM
This is a Dust Measurement Network detector node (Particulate Matter) and thus we measure PM values.
Temperature and Relative Humidity
In order to put the PM measurements in the right relation to the current weather conditions, it is essential to also measure the Temperature and the Relative Humidity.
Battery
The battery voltage shall be supervised to ease remote detector device maintenance and also to stop discharging the battery when the voltage level falls below the acceptable threshold. #21
