4 Pack Ceiling Sensor, PIR Occupancy Motion Detector for LED High Bay Light, 40 FT Ceiling and 50 FT Wall Mount Detection Diameter, Commercial/Industrial Grade

Motion Sensor Switch Ceiling MountedThis sensor employs cutting-edge passive infrared (PIR) technology and microcontroller technology, providing superior stability compared to conventional motion sensors
Easy to InstallationThis PIR Sensor is easy to install, only rotate down the sensor base on base of the LED Linear High Bay light or UFO highbay light and plug in the sensor and it is ready to use immediately
Extend Lamp Life & Energy-SavingRetains 30% of lumens in standby mode and instantly ramps up to 100% brightness when activated, maximizing energy efficiency and savings, effectively extends the life of the light
Smart Motion SensorDetection radius is 1-8m. The hold time of the motion sensor is 3min/5min/10min/15min. When the people leave the induction area, the light will be dim to 0/25%/50%/75% of full light output. Setting the "Stand-by DlM" at 0% means light full off during vacancy. Stand-by time to represents the time that the sensor will keep the light atlow dim level after the "Hold time" elapsed. Set Standby time level to 1min/30mins/60mins/+.
