WattStopper Occupancy Sensor for 120/277V
The WattStopper sensor covers up to 1200 square feet with 360-degree sensing for versatile indoor and sheltered outdoor spaces. Best for large, monitored rooms or hallways where comprehensive motion detection is needed. It is suitable for areas requiring reliable occupancy control with 120/277-volt compatibility. A potential limitation is its size; installations in tight ceilings may require more planning. Choose this for expansive coverage and proven reliability in commercial or industrial settings.
Metalux UHBS Specialty PIR Sensor
This fixture-mounted, 360-degree PIR sensor is designed for wet locations with IP65 rating. It includes a warm-up period and multiple hold-time states, offering flexibility in how lights stay on after motion detection. Best for areas where water exposure is ongoing, such as covered outdoor interiors or damp industrial zones. A limitation is that installation and wiring must respect wet-location standards. Pick this for robust protection and adaptable operation in challenging environments.
EverElectrix 360° Ceiling Occupancy Sensor
Designed for high bays and industrial ceilings, this hard-wired sensor covers 360 degrees and supports 120-277 VAC. It is best for warehouses or manufacturing facilities where ceiling height and broad coverage are critical. The sensor helps extend lamp life and save energy with adjustable time delay and light level settings. A limitation is it may be overkill for small rooms. Choose this for large, hard-to-access spaces that require precise timing controls.
Leviton PIR Ceiling Mount Occupancy Sensor
Leviton offers a cost-effective option for commercial installations where recessed ceiling units are challenging. It uses passive infrared sensing with a quick-install design that consolidates sensor and relay in one unit. Best for spaces where ceiling access is easy and quick deployment is needed. A potential limitation is reliance on recessed mounting, which may not suit every retrofit scenario. Consider this for straightforward, economical commercial projects.
Sensor Switch CMR 10 Contractor Select
The CMR series delivers 360-degree PIR sensing designed for large private offices or small rooms. It is optimized for higher ceilings and offers easy ceiling installation with included mounting hardware. Best for commercial interiors needing robust motion detection with simpler wiring. A limitation is detection performance can vary with room geometry; ensure it aligns with the intended mounting height. Choose this for practical, reliable ceiling-mount control.
ECOELER PIR Ceiling Sensor Switch
ECOELER offers a slim, hard-wired ceiling sensor with 360-degree detection and adjustable time delay, sensitivity, and light-level sensing. Best for corridors, storage areas, and pantries where a compact, discreet sensor is beneficial. A limitation is that maximum range may be less than bulkier ceiling units in very large spaces. This is a good pick for retrofits needing a slim profile with flexible configuration.
ENERLITES Low Voltage Ceiling Sensor
ENERLITES provides a 360-degree field of view for low-voltage, ceiling-mounted sensing with 1200 sq ft coverage. It targets commercial and industrial environments seeking a simple, energy-saving solution that supports incandescent, CFL, and LED lighting. Best for budget-friendly, straightforward installations in larger rooms. A limitation is reliance on low-voltage circuitry; confirm compatibility with existing wiring and controls.
Buying Guide
What environment will you install in? Wet or damp locations demand IP65-rated or higher sensors and sealed housings. For outdoor or covered areas, look for weather resistance and water exposure specifications.
What ceiling height and space size matter? Large, high-ceiling spaces benefit from 360° sensing with higher mounting heights. Small offices need compact units with straightforward wiring and quick set-up.
What control features are essential? Time delays, light level sensing, and motion sensitivity allow you to tailor energy savings. LEDs and dimmable fixtures may require sensors with compatible output types.
Is retrofitting feasible? Some sensors are designed for recessed ceilings or grids, while others fit standard ceiling boxes. Check mounting options and included hardware before purchasing.
What is the installation approach? Ceiling-mounted sensors often require access to electrical boxes and proper weatherproofing for wet locations. Consider professional installation for complex or hazardous environments.
