This issue of Specifier Reports highlights occupancy sensors for industrial and commercial use and provides guidance for equipment selection and successful installation. It explains performance characteristics such as coverage area, coverage pattern, field of view, sensitivity, and time delay. It covers passive infrared, ultrasonic, and dual-technology (hybrid) occupancy sensors. Application and economic considerations for specifiers are discussed, and the report provides manufacturer-supplied data and brand-name performance results. The use of occupancy sensors in the U.S. has increased dramatically over the past ten years. Manufacturers have introduced many new products designed to address some of the known problems with occupancy sensors, such as failure to detect small motions and inappropriate switching of lamps.
