The latest generation of Intra-Sewi KNX presence detectors from Elsner Elektronik have an integrated brightness sensor. The room brightness, like the presence of people, can be evaluated for the light control integrated in the device. The lighting is thus controlled according to requirements and in an energy-saving manner.
Intra-Sewi KNX is also available with additional sensors for temperature and humidity. Heating, cooling and ventilation are then automatically controlled.
The Intra-Sewi KNX sensors have been developed for ceiling installation in buildings with KNX automation. They integrate almost flush into the ceiling and reflect the modern interior design in their real glass surface. Classic white or trendy black are available as colours. Installation is carried out either with clamps in hollow ceilings or alternatively in a socket.
For surface-mounted installation, Elsner Elektronik offers Mini-Sewi KNX sensors with the same measuring and control functions.
