Feature: 1. 360 Degree View Coverage: Covers an area of approximately 530 square feet with 360 degree field of view. Ideal coverage when installed at an 8 foot height. For indoor use only. 2. Customizable Delayed Off Time Settings: The delay off time setting can be adjusted between 8 to 12 minutes, allowing customized settings for maximal cost savings. 3. LED Indicator for Detected Motion: The LED indicator light will blink when the sensor detects motion, validating the power location and functionality of the sensor during installation. 4. Doppler Principle Based Microwave Sensor: The microwave sensor operates on the principles of Doppler effect, emitting and receiving high frequency microwave signals to accurately perceive object motion. The signal amplification and microcontroller program intelligently identifies and controls the on (illumination) and off (extinguish) of the load light. 5. Radar Principle Application: This microwave sensor emits microwave signals to detect moving objects, the same way a radar speed detector works. Widely used in aerospace fields, the radar principle allows for accurate and robust performance.
