How Do Motion Sensor Night Lights Work?
Modern plug-in motion sensor night lights use passive infrared (PIR) technology to detect body heat and movement within 10-15 feet. When activated, they instantly illuminate bright LED bulbs (typically 2-10W) without manual switching - creating the ultimate no wiring needed night light solution. Most models feature:



Adjustable sensitivity (for pets/children)



Time-delay settings (15sec to 10min operation)



Twilight sensors (only activate in darkness)
