Abstract
A multiple sensing technology-based occupancy sensor including a unique sensor case assembly and sensor mounting scheme. The result is an occupancy sensor that is adjustable to provide broader ultrasonic pattern coverage and an ability to focus infrared energy from a variety of directions. In addition, the unique mounting scheme permits simple and efficient installation of the occupancy sensor.
