To power the air quality meter can be operated directly via the micro USB port on the back. The built-in battery with the air quality meter is charged via this interface. Thus, the air quality meter is versatile. It should be noted that the measured values settle within 24 hours after switching on the air quality meter.
N.B. the meter is designed to be operated by mains power, and will run only a few hours by the battery.
