Abstract
Disclosed herein is a lighting system configured to obtain an indicator data of a RF signal generated at a number of times in an area. When each such time is a current time, the indicator data generated at the current time is compared with the indicator data generated at a preceding time to determine a rate of change, and the indicator data generated at the current time is compared with a baseline indicator data at an earlier time to generate a difference value. The lighting system is configured to determine an indicator data metric based on the rate of change and the difference value and compare the indicator data metric with one of a rising transition threshold or a falling transition threshold to detect one of an occupancy condition or a non-occupancy condition in the area.
