Other methods include microwave sensors, which emit low-power microwaves and detect changes in occupancy, and camera-based sensors, which take multiple images of the coverage area per second. Dual-technology (DT) sensors combine PIR with ultrasonic or acoustic sensing. The most common single-technology methods are passive infrared (PIR) and ultrasonic (US). Shown here is a coverage pattern for a wall switch ultrasonic sensor. The value is typically a maximum, which may be adjusted based on sensitivity setting, room dimensions, mounting height, presence of obstacles and other factors. This allows meaningful product comparison. NEMA WD-7 offers testing and reporting methods for coverage areas and patterns, which compliant manufacturers report in their literature. Coverage shape is the resulting shape of these boundaries, which may be a circle, rectangle, ellipse, tear drop, etc. Coverage area defines the boundaries within which the sensor can detect motion. The resulting coverage is expressed as coverage area and pattern. The sensor’s sensitivity defines at what distance it can detect major (i.e., body) and minor (i.e., hand) motion. While ON/OFF is more common, light reduction is well suited to applications where the lights must stay ON but are frequently unoccupied, such as this stairwell, or where the lamp does not start quickly, as in the case of HID lamps. Occupancy and vacancy sensors may turn the lights OFF or reduce the lighting via stepped switching or dimming. Full-ON sensors provide convenience, which may be regarded as an amenity.

Manual- and partial-ON sensors tend to save more energy because the occupant may want to leave the lights OFF or at a lower level. Full-ON sensors activate the lights at full output. Partial-ON sensors activate the lights to a designated level such as 50%, and the occupant then uses a switch to bring the lights to full output. Manual-ON sensors (also called vacancy sensors) require the occupant to turn the lights ON using a manual switch, which may be integral to the sensor (shown here is an example). The majority of commercial building energy codes require manual- or partial-ON operation. Occupancy sensors may be specified as manual-, partial- or full-ON devices.
