The Efento 7813 wireless temperature, humidity and air quality logger is designed to monitor indoor climate conditions.
The device measures air quality based on the concentration of volatile organic compounds (VOC). It also calculates IAQ (Indoor Air Quality), which represents air quality in the room based on the Bosch patented algorithm.
The sensor also measures the temperature and relative humidity of air. This, in combination with the VOC concentration, gives a full picture of room conditions.
