Task Lighting & Power Doppler Motion-Sensor Switch

November 22, 2022

Task Lighting & Power, a Hardware Resources company, has introduced a new Doppler motion-sensor switch that can be installed behind a non-metallic barrier up to 2 inches thick and detect motion within a 15-ft. range. Unlike traditional infrared sensors that require a direct line of sight to activate, the Task Lighting Doppler motion-sensor switch emits harmless waves that reflect off nearby objects. The sensor looks for a Doppler (frequency) shift in the wave when it returns to the detector, which indicates that the wave has hit a moving object. When the sensor detects a Doppler shift, it activates to turn on the light. 

The Task Lighting & Power Doppler motion-sensor switch is an excellent option for residential and commercial applications. Residential designers embracing Universal Design principles can incorporate the sensor anywhere hands-free lighting activation would be not only a nice aesthetic but also a safety feature. Specifically, the Doppler motion sensor can be installed behind a valance or inside a cabinet to activate a night light. The Doppler motion sensor features a selectable light timer that can be set from 60 to 240 seconds and a smooth on/off feature that gradually brightens or dims the light as it turns on or off.
