Description

The BT31M Microwave Radar Motion Sensor Occupancy Body Motion Detector is an advanced, high-performance sensor designed for body motion detection in a wide range of applications, including smart lighting, HVAC automation, and security systems. Using microwave radar technology, the BT31M detects motion through walls, glass, and other materials, providing highly accurate and reliable occupancy detection even in complex environments.

With its sensitive radar sensing, the BT31M can detect human presence and movement over large areas, making it ideal for use in offices, restrooms, warehouses, and public spaces. The sensor is energy-efficient, contributing to energy savings by controlling lighting and climate systems based on occupancy. It features a compact design for easy integration into ceiling or wall mounts, and its adjustable sensitivity and time delay settings allow for customization according to specific needs. This makes it perfect for creating automated systems that enhance convenience and reduce energy waste in both residential and commercial spaces.
