Abstract

A system and associated methods of operation for regulating an environmental variable (such as ambient room temperature) within a target zone. The system includes an occupancy sensor configured to monitor the target zone and determine a number of inhabitants present within the zone. The occupancy sensor generates an occupancy signal communicating the number of detected inhabitants to an environmental control system. Upon receiving the occupancy signal, the environmental control system regulates an environmental variable within the zone based on the number of inhabitants present in the zone.
