Internal Temperature and relative internal humidity
Temperature and relative humidity are measured by sensors placed inside the device enclosure.
These measurements can be used to monitor if the device is working in recommended conditions.
Battery condition
Battery voltage is used to monitor the operating condition of the device. This data allows the user to
detect anomalies (like a sudden drop) and track the current state of the battery based on the voltage
drop over time compared to the initial voltage.
Differential pressure
Differential pressure is measured by two separate sensors. One of them provides information about
air pressure before the filter; the second measures air pressure after the filter. Measurements inform
users about airflow and air quality.
