Abstract

Embodiments of the present invention include an occupancy sensing unit configured to monitor an environment illuminated by a lighting fixture. An inventive occupancy sensing unit may include an occupancy sensor to detect radiation indicative of at least one occupancy event in the environment illuminated by the lighting fixture according to sensing parameters. The occupancy sensor can be coupled to a memory that logs sensor data, which represent the occupancy events, provided by the occupancy sensor. A processor coupled to the memory performs an analysis of the sensor data logged in the memory and adjusts the sensing parameters of the occupancy sensor based on the analysis.

Claims

1. An occupancy sensing unit to monitor an environment illuminated by a lighting fixture, the occupancy sensing unit comprising:

A) at least one occupancy sensor to detect radiation indicative of at least one occupancy event, in the environment illuminated by the lighting fixture, according to sensing parameters;

B) a memory, operatively coupled to the at least one occupancy sensor, to log sensor data, representing the at least one occupancy event, provided by the at least one occupancy sensor; and

C) a processor, operatively coupled to the memory, to;

C1) perform an analysis of the sensor data logged in the memory, and

C2) adjust the sensing parameters of the at least one occupancy sensor based on the analysis of the sensor data logged in the memory.
