Motion Sensors

Motion sensors help automate lighting based on detected movement or occupancy. Common commercial uses include rooms, cubicle areas, warehouses, manufacturing floors, garages, parking lots, gyms, cold-storage spaces, and high-mounted lighting applications; compact motion-activated sensor lights also add illumination in attics, bathrooms, and closets.

Motion Sensor Buying Guide

Choose a motion sensor by first matching its mounting location, sensing technology, electrical arrangement, and coverage needs to the lighting application. This category includes ceiling-mounted room sensors, fixture- and junction-box-mounted modules, high-bay sensors, and compact motion-activated LED lights.

Use Cases

Match the sensor to the space

Ceiling-mounted 360° sensors suit rooms and cubicle spaces. High-bay and fixture-mounted models fit warehouses, manufacturing areas, garages, parking lots, gyms, cold storage, and site or area locations. Compact LED sensor lights are intended for attics, bathrooms, and closets.

How to Choose

Start with mounting and power

Compare ceiling, grid, fixture-end, fixture, and junction-box mounting options. Then confirm whether the installation needs line-voltage switching, multi-voltage operation, 24VDC operation, or compatible low-voltage power arrangements and power packs.

Applications

Select coverage for the lighting layout

Look for 360° sensing where all-around room or fixture coverage is needed. For high-mounted lighting, compare stated high-mount capabilities, including options for installation heights up to 40 ft or coverage up to 45 ft. Interchangeable lenses can support general-area or aisleway-focused coverage.

Additional Information

Compare control and environmental features

Available features include adjustable time delays, push-button programming, self-contained relays, daylight sensing, selectable operating modes, lamp burn-in timers, and indoor or outdoor placement. Temperature range, housing construction, and separately selected lenses also vary by model.

Planning Guide

Plan the right fit before choosing

1. Choose a sensor format

Select mounting that fits the lighting installation

Ceiling-mount sensors provide room coverage from above and include options for drop ceilings or ceiling grids. Fixture-mount and end-fixture-mount modules install directly at compatible fixtures, while some also mount at a compatible junction box. High-bay fixture sensors are designed for high-mounted lighting applications.

  • Ceiling-mounted options for enclosed rooms, small rooms, and cubicle spaces
  • Fixture and junction-box mounting for compatible lighting installations
  • Fixture-end mounting through an extended 1/2 in. chase nipple
  • High-bay options for individual fixture control
2. Compare sensing and control needs

Match detection technology to the activity in the area

PIR sensors respond to infrared-energy changes as occupants move. Dual-technology models combine PIR with microphonics to help recognize continued occupancy and may include automatic gain control to filter steady background noise. Time-delay adjustment is offered across several sensor types, while certain models add direct line-voltage switching or require compatible power arrangements.

  • PIR detection for movement-based occupancy sensing
  • Dual technology for motion and ongoing human activity detection
  • Adjustable shutoff delays, including a 30-second to 20-minute range on one high-bay option
  • Self-contained relay options that avoid a separate power pack
3. Account for the environment and added functions

Review daylight, temperature, and lighting-control details

For indoor or outdoor fixture applications, compare voltage compatibility, operating temperature range, and housing construction. Some fixture-mounted modules offer upward- and downward-looking daylight sensing, while another provides a separate downward-looking daylight lens option. Selected ceiling sensors include a 100-hour lamp burn-in timer.

  • 120, 277, or 347 VAC options at 60 Hz on selected modules
  • 24VDC option for compatible low-voltage systems
  • Operating ranges represented from -40 to 149°F and 32 to 149°F
  • Impact-resistant or high-impact plastic housings on selected modules
FAQ

Common questions before buying

What is the difference between PIR and dual-technology motion sensors?

PIR sensors respond to movement through changes in infrared energy. Dual-technology models combine PIR with microphonics to help identify motion and continued human activity.

Are there motion sensors for high-bay lighting?

Yes. High-bay fixture-mount PIR options are represented for high-mounted lighting, with stated capabilities including installation heights up to 40 ft or coverage up to 45 ft, depending on the model.

Can these sensors be installed on a fixture or junction box?

Selected occupancy sensor modules support direct fixture or compatible junction-box installation. Some high-bay models install through a 1/2-inch fixture or junction-box knockout.

Which motion sensor options support outdoor locations?

Selected fixture-mount modules support indoor or outdoor, low- or high-mount installations. Review each model's voltage, temperature range, lens options, and mounting requirements for the specific location.
