This E27 motion sensor switch is one of those smart home upgrades that just makes life more convenient! Simply screw it into any standard E27 light socket, then screw your LED bulb, energy-saving lamp, or other lighting into it - no wiring required. The infrared sensor detects movement within a 110-degree angle and up to 6 meters away, automatically turning on your lights when someone enters the room. The adjustable delay timer lets you set how long the light stays on - choose from 15 seconds, 45 seconds, or 4 minutes depending on your needs. The photosensitive setting is super useful too - you can adjust the lux sensitivity from 2-2000 lux, meaning you can set it to only work in darkness or allow it to operate during daytime too. Made from PC flame retardant material for safety and durability, this switch handles AC100V-265V voltage and supports bulbs up to 50W. The recommended installation height is about 3.5 meters for optimal coverage. Perfect for hallways, staircases, closets, bathrooms, garages, or any space where you want hands-free lighting that saves energy. The compact 86x86x30mm size stays discreet while providing reliable motion-activated lighting. Whether you want convenience, security, or energy savings, this motion sensor switch delivers smart lighting control without any complicated installation or smart home setup required.
