DT-300, Occupancy Sensor

DT-300 Occupancy Sensor – Low Voltage Dual Technology Ceiling Sensor The DT-300 Occupancy Sensor by WattStopper is a low voltage dual technology sensor designed for ceiling tile mounting. Combining passive infrared (PIR) and ultrasonic sensing technologies, it provides reliable occupancy detection with 360-degree coverage up to 1000 square feet. Ideal for commercial lighting control applications, this sensor is suited for classrooms, open offices, computer rooms, and other spaces where false triggers from a single technology are a concern. It integrates easily with low-voltage power packs and supports both automatic and manual-on lighting operation, making it a valuable component for electrical distributors and lighting solutions providers.
