Optical system (movement detector)
Fig. 24: Optical system (movement detector)
By means of lenses, mirrors and sensors, the area to be monitored is divided into numerous
fields or so-called sectors. If a person moves from one sector to the next, this movement is
detected.
Light measurement
Fig. 25: Brightness sensor
The devices of ABB are fitted with an ambient light measurement. This extends the movement
detection process by one brightness-value threshold.
The brightness-value threshold determines the luminosity from which the light switches on. If
the surrounding light is brighter that the set brightness-value threshold, the light does not switch
on if movement is detected.
