Metalux UHBS Wet Location Occupancy Sensor
The Metalux UHBS is a plug-and-play PIR occupancy sensor designed for wet locations. It features a 360-degree sensing area and IP65-rated protection, suitable for bathrooms, utility rooms, and outdoor entryways. The unit includes a warm-up period after power-up and offers multiple hold-time and dimming options, enabling flexible lighting control. Its wet-location rating helps prevent ingress in damp environments while maintaining reliable motion detection for energy savings. Installation is straightforward for compatible fixtures, reducing labor in commercial and residential projects alike.
Diversitech Wet Switch Flood Detector
The Diversitech WS-1 flood detector is designed to prevent water damage by detecting moisture and quickly triggering alerts or shutoffs. It includes hydrophilic polymer fibers and integral feet to manage water draw and minimize corrosion. The detector uses standard 24VAC control wiring for quick integration into existing irrigation, HVAC, or building management circuits. This sensor is ideal for basements, laundry rooms, and other spaces prone to leaks where early detection can reduce costly water damage.
Maxxima Ceiling Mount 360 Degree PIR Sensor
The Maxxima ceiling-mounted PIR sensor provides full 360-degree coverage for spaces up to 15 feet high. It is compatible with 120V–277V circuits and supports high-load applications (up to 800W at 120V and 1200W at 277V). Designed for both commercial and residential spaces, its wide detection range makes it suitable for hallways, foyers, or large rooms. The unit integrates easily with existing lighting systems and supports LED or traditional lighting loads, improving energy efficiency without compromising convenience.
Leviton PIR Ceiling Mount Occupancy Sensor
The Leviton ceiling-mounted PIR sensor offers a cost-effective solution for commercial and institutional installations where recessed units are impractical. It uses a segmented Fresnel lens to detect occupancy and includes a built-in relay for straightforward wiring. The compact design reduces installation labor and enables reliable automatic lighting controls in offices, classrooms, and storage areas, while maintaining a clean, unobtrusive ceiling appearance.
Maxxima Occupancy Vacancy Motion Sensor Wall Switch
This Maxxima wall switch supports both occupancy and vacancy modes, offering flexibility for energy-saving strategies. The dual operation includes a manual-on or automatic-on option with a green LED backlight for easy status visibility. With adjustable time delays (1–30 minutes) and sensitivity settings, it adapts to hallways, restrooms, and other spaces where light levels and occupancy patterns vary throughout the day.
ECOELER PIR Ceiling Sensor Switch
The ECOELER PIR ceiling sensor provides 360-degree detection with a slim form factor suitable for high bays and large rooms. It features adjustable time delays, sensitivity, and ambient light sensing to tailor behavior from hallways to storage facilities. Its IP-rated construction helps protect electronics in damp environments, while quick installation supports both residential and commercial projects that demand dependable occupancy sensing and energy efficiency.
ECOELER Ceiling Occupancy Motion Sensor Switch
The ECOELER ceiling sensor combines robust 360° detection with high bay suitability. It is designed for large, open spaces and hallways, where predictable motion detection is essential for saving energy. The unit’s adjustable time delay and sensitivity enable precise control over lighting behavior, and its UL/FCC listings ensure compliance with electrical safety standards in both commercial and residential environments.
Buying Guide: Key Purchase Considerations
When selecting a wet-location occupancy sensor, consider these factors to ensure a suitable match for your space:
- Wet-location rating and enclosure protection: Look for IP ratings and enclosure types that guard against water exposure, especially outdoors or near sinks and showers.
- Detection range and mounting height: Ceiling-mounted sensors often require higher mounting heights; verify 360° or directional detection fits the area’s layout.
- Power requirements: Confirm voltage compatibility (commonly 120V–277V) and whether the device supports LED, CFL, or incandescent loads.
- Operating modes and timing: Occupancy vs. vacancy modes, time delays, and dimming or switching capabilities affect user experience and energy savings.
- Installation ease and integration: Plug-and-play options or quick-relay assemblies reduce labor; ensure compatibility with existing fixtures and wiring.
- Ambient light sensing: For areas with daylight, a light-sensing feature helps prevent lights from turning on unnecessarily.
- Durability and certifications: UL/FCC listings and robust mechanical build are important for long-term reliability in moist environments.
Comparative Notes
- Plug-and-play designs provide quick deployment but may offer fewer programmable options than dedicated fixtures.
- Ceiling-mounted sensors are ideal for large, open spaces with high ceilings, while wall-mounted models suit smaller or cramped areas.
- Flood-detector style devices prioritize water protection and leak detection over lighting control, offering complementary safety benefits in wet spaces.
- Ambient light sensors help tailor performance to daylight conditions, maximizing energy savings without compromising visibility.
