Occupancy/Vacancy Sensors, Ceiling Switch Adaptive Dual Technology, 2 Circuit, 120/277V AC, Office White

Ultrasonic (US) technology senses occupancy by bouncing sound waves (32 kHz - 45 kHz) off of objects and detecting a frequency shift between the emitted and reflected sound waves. Movement by a person or object within a space causes a shift in frequency, which the sensor interprets as occupancy. While US occupancy sensors have a limited range, they are excellent at detecting even minor motion such as typing and filing, and they do not require an unobstructed line-of sight. This makes US technology sensors ideal for an application like an office with cubicles or a restroom with stalls.
