![CDATA[The Vari KNX 3L sensors for the KNX building bus system measure brightness. Other models also measure temperature, humidity and air pressure and receive the GPS signal for time and location. All measured values can be used to control limit-dependent switching outputs. The states can be linked using AND logic gates and OR logic gates. Multifunctional modules change input data as required by calculations, querying a condition or converting the data point type. The sensors, evaluation electronics and the electronics of the bus connection are housed in the compact housing.]]>
