Dual Technology Occupancy Sensor

The CM-PDT-9 is a Dual Technology Occupancy Sensor with Passive Dual Technology (PDT) first sees motion using Passive Infrared (PIR) detection and then engages Microphonics™ to hear sounds that indicate continued occupancy. This patented technology uses Automatic Gain Control (AGC) to dynamically self-adapt a sensor to its environment by filtering out constant background noise and registering only noises typical of human activity.

This 360° occupancy sensor provides line-of-sight PIR detection of small motion in a circular pattern, and combines overlapping Microphonics™ coverage for detection of occupants working in cubical spaces. Bathrooms, large storage areas with shelving, and libraries with study carrels are also easily and cost-effectively controlled by the CM-PDT-9.
