Our product line offers innovative technologies that help save time on the job site, while adding key lighting control features to the application space. SensorSwitch products include innovations such as convertible neutral, miswire protection, self-calibrating daylight controls, visible light programing, and advanced detection technologies.
SensorSwitch sensors are available with either of two detection technologies: passive infrared (PIR) or passive dual technology (PDT).
Passive Infrared Technology (PIR)
PIR sensors detect changes in the infrared energy given off by occupants as they move within the field-of-view of the sensor. The sensor “sees” the heat given off by the human body as it moves in and out of the beams and triggers the occupancy mode. The sensors are fine-tuned to detect small motions even at great distances, while still preventing false triggers. All SensorSwitch sensors have PIR technology.
Passive Dual Technology (PDT)
PDT is a powerful combination of two detection technologies: Passive Infrared and Microphonics™. The sensor will first detect occupancy using Passive Infrared, and then engages Microphonics technology which uses an internal microphone to detect sounds that indicate continued occupancy. This combination of technologies is perfect for rooms with partitions or furnishings that would prevent infrared sensors from "seeing" occupants on a continuous basis.
What are some advantages of SensorSwitch detection technologies over conventional sensors that detect motion by emitting ultrasonic sound waves?
