The Sewi KNX indoor sensor monitors not only the presence of persons and the brightness, e.g. to switch light in an energy-optimized way, but also measures temperature, air humidity and CO2 for ambient climate control.
The sensor is mounted on the ceiling or wall and is available in different variants as single or combined unit. The different models offer additional functions: e.g. the temperature sensors have got a room climate controller as well as summer compensation for cooling, which means that the target temperature in the room is adapted to the outdoor temperature.
The devices also feature logic gates and multifunctional modules for transformation and conversion of data.
