Legrand sensors are brilliant solution for smart lighting management which is both efficient and energy-saving.

Legrand provides a wide range of product lines for sensor, including motion sensor, occupancy sensor, ultrasonic sensor, etc.

Different areas in the building demand different lighting. Installation of Legrand sensors would manage the suitable lighting levels and therefore, help to save energy and reduce electricity consumption.

Smart lighting management solution using Legrand sensors also help to reduce unnecessary lighting, especially for areas like hallways or restrooms.

Legrand sensors are high-quality products integrated with modern technology:

Passive infrared technology (PIR)

PIR technology senses occupancy by detecting the difference between heat emitted from the human body in motion and the background space.

Ultrasonic technology

Using the Doppler principle, ultrasonic sensor work by bouncing ultrasonic sound waves off objects in an area and measuring the time it takes for the waves to return. Movement by a person in the area causes the sound waves to return at a changed frequency, resulting in a Doppler shift and occupancy detection.

Dual technology

While PIR and ultrasonic sensor provide optimal control for a variety of spaces,
some applications pose difficulty for single technology sensor. Therefore, Dual Technology is created – a combination that takes advantage of the best features of both PIR and ultrasonic technologies.
