Abstract
An occupancy sensor device for monitoring a space includes a transmitter portion and a receiver portion. The receiver portion is located remotely from the transmitter portion. To enable reliable detection of occupancy within the monitored space, an estimate of the signal transmitted by the active sensor in the transmitter portion is compared to the signal received by the transmitted portion.
