W-500A Ultrasonic Ceiling Occupancy Sensor for Smart Lighting, 180 Degree Coverage Up To 900 Sq Ft, NoBrainer Install With One Inch Back Housing And Flying Leads, Built In Light Sensor, Tactile Button, Dual 120/277 VAC

Ultrasonic Ceiling Occupancy Sensor for Smart Lighting
✔️ 180° coverage up to 900 ft², 1 in back housing, built-in light sensor

The ultrasonic ceiling occupancy sensor is designed to drive smart lighting by detecting room presence and ambient light levels. It is typically installed in ceilings for commercial spaces like offices, classrooms, hallways, and retail areas to ensure lights run only when people are present and daylight is insufficient.

✅ 180° coverage up to 900 ft² (83.6 m²)
✅ Built-in ambient light sensor for daylight harvesting
✅ 1 in shallow back housing with flying leads and tactile button
✅ Dual voltage operation: 120/277 VAC

💡 What is an ultrasonic ceiling occupancy sensor used for in smart lighting systems?

Smart lighting control is achieved by detecting occupancy and ambient light to automate lighting, saving energy. - Ultrasonic motion detection helps determine room presence - Built-in ambient light sensor prevents lights from turning on in daylight - Works with 120/277 VAC circuits for flexible retrofits ✝️
