Combined Sensor Light and Presence detection

Sensors for measuring ambient light and occupancy, to be used in combination with CAREL or third-party electronic controllers. These sensors contribute to ensuring intelligent management of electrical loads, rationalising power consumption and consequently saving energy.

The combined light and presence detection sensor DPWA series for indoor and outdoor installation are instrument that detects motions and light intensity as well as the presence of persons and is used to recognize environment conditions.

The output signal is 4...20 mA for light intensity and has a switching (changeover contact SPDT) output for the detection of motions. Those combined sensors are installed, where is necessary use a device for the observation and recognition of

conditions and for a motion dependent control of room functions, e.g. as motion detector to lower temperatures in unused

rooms.
