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) and calculates IAQ (Indoor Air Quality) representing air quality in the room based on the Bosch patented algorithm. Volatile organic compounds are substances derived from many indoor products, including from paints, cleaning agents, solvents, alcohol or glue. Some volatile organic compounds are carcinogenic. In addition, the sensor measures the temperature and relative humidity of air, which, in combination with the VOC concentration, gives a full picture of the room conditions.

You can use a free mobile application to configure the device and read the data from its memory. If you add Efento Gateway, you can build a remote monitoring system.
