Radio controlled presence detector
March 2010
Sensors & Transducers
The Sensolux solar presence detector from PEHA provides environmentally friendly light control in private and commercial buildings, lights being switched on when presence is detected. Once a specified light value has been reached, unnecessary lighting can be switched off saving energy over the long-term. The presence detector has proved to be a valuable asset during planning; the lack of any wiring or batteries reduces cable routing, plastering and painting costs considerably.
The unit derives its energy from solar cells; when fully charged, the detector can run for several days in complete darkness. The presence sensor registers the presence of persons and measures the current light level. This data is sent by radio to the Sensolux receiver. The parameters are set on the 2-channel receiver and two series of lights can be controlled individually. For use in rooms without daylight, the presence detector can optionally be equipped with two alkaline batteries (AAA) with a lifespan of eight to 10 years.
The user can at any time switch the lighting on or off via conventional or Easyclick radio control buttons. In semi-automatic mode, the lighting is switched on manually and switched off via the presence detector. The light-on time, light level, daylight or twilight parameters can be set in both modes.
By utilising EnOcean radio technology, the system offers maximum convenience and comfort when automatic and energy efficient lighting control is required.
