The ECOELER Ceiling Occupancy Motion Sensor Switch is a passive infrared sensor designed for high bay fixture mounting, offering 360-degree ceiling automatic light control. Constructed with robust housing materials, the unit is engineered for extended durability in commercial and industrial environments. Its internal components are built to UL and FCC standards, ensuring reliable operation and electromagnetic compatibility. The sensor requires a neutral wire for installation, making it suitable for retrofit or new setups where neutral is available. Operating at 120/277VAC, it accommodates common voltage configurations found in warehouses, factories, gymnasiums, and large retail spaces. The passive infrared technology detects body heat and movement across the full 360-degree coverage area, automatically switching lights on when occupancy is detected and off after a preset timeout. This hands-free operation reduces energy waste and extends lamp life. The switch’s housing is made from flame-retardant materials, providing an extra layer of safety. Its compact profile allows flush mounting on standard ceiling junction boxes or high bay fixtures. The detection range and time delay settings can be adjusted via onboard controls, though the exact adjustment method is detailed in the installation manual. The sensor is designed for steady performance under varied ambient temperatures, delivering consistent triggering without false activation from HVAC drafts or minor movements. The unit’s surface is crafted to resist dust accumulation, maintaining sensitivity over time. As a value-priced solution compared to similar commercial-grade sensors, it provides essential occupancy-based lighting management without premium pricing. The product is particularly well-suited for facilities seeking to meet energy code requirements for automatic shutoff controls. Its straightforward wiring and mounting design reduce installation time for electricians. The sensor does not incorporate wireless connectivity, focusing instead on reliable wired operation. With neutral wire required, it is not compatible with circuits lacking a neutral, so pre-installation verification is essential. The switch’s passive infrared technology does not emit any signal, making it safe for environments where radio interference must be avoided.

The ECOELER Ceiling Occupancy Motion Sensor Switch delivers fundamental motion detection for high bay ceilings with a balance of affordability, compliance, and build quality.
