The PIR Motion Sensor LED Dimmer Switch is a smart solution for controlling your LED light strips and other lighting systems automatically. Designed for both 12V and 24V power supplies, this infrared sensor detects movement within a 5-8m range, ensuring your lights only turn on when needed. The sensor features a 120-degree viewing angle, providing a wide field of detection, making it suitable for larger rooms or spaces with multiple entry points.This infrared detection controller allows you to adjust the delay time for light turn-off, from 1 to 10 minutes, by simply turning the knob on the back. Whether you need the light to stay on for a few seconds or several minutes after detecting movement, the adjustable delay offers flexibility for different needs.
