Occupancy and Vacancy Sensors

Occupancy and Vacancy Sensors maximize energy savings, ensuring that lights are turned off or to a lower level when spaces are unoccupied or adequate daylight exists. Sensor options include passive infrared, ultrasonic, and a combined dual technology of both passive infrared and ultrasonic. For applications from warehouses and parking garages to offices and classrooms, Wattstopper’s energy-efficient occupancy and vacancy sensors offer the ultimate convenience and security for commercial spaces.
