The sensors Vari KNX 3L and Vari KNX T for the KNX building bus system measure brightness and/or temperature. Further models measure additionally temperature, humidity and air pressure and receive the GPS signal for time and position.
All values can be used for the control of limit dependent switching outputs. States can be linked via AND logic gates and OR logic gates. Multi-function modules change input data as required by means of calculations, querying a condition, or converting the data point type.
The compact housing accommodates the sensors, evaluation circuits and bus-coupling electronics.
