Hands-Free Control with Legrand Motion Sensors
Leaving lights on is a thing of the past. Legrand motion sensors bring intelligence to your switching, ensuring lights are on only when you need them. Whether you are carrying a laundry basket with full hands or managing energy costs in a large office building, Legrand offers the industry's most reliable sensing technology. From the sleek residential SensaSwitch™ to the commercial-grade Wattstopper® line, discover how automatic lighting control can simplify your life and lower your utility bill.
Choosing the Right Legrand Occupancy Sensor & Vacancy Switch
Legrand offers different sensor types tailored to specific room needs. Understanding the difference ensures you get the right performance.
1. Occupancy Sensors (Auto-On / Auto-Off)
The ultimate convenience. The Legrand occupancy sensor detects when you enter the room and turns the lights on automatically. When you leave, it waits for a preset time delay and turns them off.
- Best For: Laundry rooms, garages, pantries, and mudrooms where your hands are often full.
2. Vacancy Sensors (Manual-On / Auto-Off)
Maximum energy savings. You must manually press the switch to turn the lights on, but the vacancy sensor will automatically turn them off when the room is empty. This prevents lights from turning on unnecessarily (like when you just walk past a door).
- Best For: Bedrooms and media rooms where you don't want lights triggering every time you move. Note: Required by code (Title 24) in many residential spaces.
3. Wattstopper® Commercial Control
The pro's choice. Legrand Wattstopper sensors are the benchmark for commercial energy management. Available in wall switch and ceiling-mount capabilities, they utilize advanced Dual Technology (PIR + Ultrasonic) to detect even slight movements in offices and restrooms, ensuring lights never go off on an occupant working quietly at a desk.
Advanced Features: Legrand SensaSwitch & Wattstopper
- Passive Infrared (PIR): Detects heat signatures in motion. Standard in most Legrand motion sensor switches for reliable people detection.
- Microban® Protection: Many residential radiant® sensors feature antimicrobial protection, keeping the switch surface cleaner in high-touch areas like bathrooms.
- Adjustable Time Delay: You control how long the lights stay on after you leave—from 30 seconds to 30 minutes.
- Ambient Light Detection: Smart sensors can sense if there is enough natural daylight in the room and keep the lights off to save energy, even if motion is detected.
