Wireless with light sensor and occupancy detector is intended to be used to control the output level of Poseidon receivers P8 R1 DALI N a P8 R 01-10 N according to the intensity of external light. One sensor can control two receivers at different levels and thus optimize the performance of luminaires placed closer or further away from sources of outdoor light. The occupancy detector which is integrated in the device switches off the lights in case the observed area remains vacant. 
The controller is used in ceiling mountings, in holders of MR16 halogen bulbs.
