Why Use Occupancy Sensors?
Let’s keep it simple—these devices pay for themselves.
- 💡 Reduce Energy Costs – Lights only run when needed
- ⚡ Improve Efficiency – Ideal for commercial & industrial spaces
- 🏢 Meet Energy Codes – Supports Title 24, IECC, and local compliance
- 🔧 Easy Integration – Works with LED fixtures, wall packs, high bays, and more
- 🧠 Smart Automation – No switches, no guesswork
Types of Occupancy Sensors We Offer
Not all sensors are the same—choosing the right one matters.
Passive Infrared (PIR) Sensors
Best for spaces with a clear line of sight like offices, hallways, and restrooms. Detects heat movement.
Ultrasonic Sensors
Great for areas with obstacles like warehouses or rooms with partitions. Detects motion using sound waves.
Dual Technology Sensors
Combines PIR and ultrasonic for maximum accuracy. Ideal for high-traffic or critical areas where false triggers aren’t an option.
Ceiling Mount Sensors
Perfect for open areas like conference rooms, storage areas, and large offices.
Wall Switch Sensors
Replaces standard switches—easy retrofit for smaller rooms.
High Bay / Fixture-Mounted Sensors
Designed for warehouses and industrial lighting like LED high bays and canopy fixtures.
Where Are Occupancy Sensors Used?
You’ll find these just about everywhere:
- Offices & conference rooms
- Warehouses & distribution centers
- Restrooms & locker rooms
- Stairwells & hallways
- Parking garages
- Schools & hospitals
Anywhere lights don’t need to stay on 24/7—these make a difference.
Occupancy Sensors vs. Vacancy Sensors
Quick tip:
-
Occupancy Sensor = Lights turn ON automatically
-
Vacancy Sensor = Lights turn ON manually, OFF automatically
Many building codes (like Title 24) require vacancy sensors in certain spaces—so choosing the right type matters.
Key Features to Look For
When selecting an occupancy sensor, keep an eye on:
- Detection range & coverage area
- Mounting type (ceiling, wall, fixture)
- Time delay settings
- Daylight harvesting capability
- Voltage compatibility (120–277V or 347V)
- Dimming & 0-10V control options

Frequently Asked Questions
Do occupancy sensors really save money?
Yes—lighting can account for a large portion of energy use. Sensors can reduce lighting energy costs by up to 30–60% depending on usage.
Can occupancy sensors work with LED lights?
Absolutely. Most modern sensors are designed specifically for LED fixtures and support dimming controls like 0–10V.
Do I need a different sensor for a warehouse vs. office?
Yes. Warehouses typically need high bay or ultrasonic sensors due to ceiling height and obstructions, while offices usually work well with PIR or wall switch sensors.
Are occupancy sensors required by code?
In many cases, yes. Energy codes like Title 24 (California) and IECC require lighting controls in commercial buildings.
What is daylight harvesting?
It’s a feature that dims or turns off lights when enough natural light is available—further increasing energy savings.
