SEOBIOG MR-SK50A Auto ON/OFF Light Control Sensor with Voice/Sound Detection: Voice/sound activation within 20-23 feet
This 220V auto on/off light control sensor is for homeowners who want to save energy and simplify lighting in hallways, closets, or garages. While many sensors focus on security, this one offers convenience by eliminating the need to fumble for switches in the dark.
The sensor detects sound at 50-70 decibels within 6 meters, so it turns on when you walk in with groceries, not just from loud noises. It works with LED downlights, ceiling lamps, and bulbs up to 60W, and the 40-second delay ensures lights stay on as you move through the space. Compatible with Alexa for voice control, it provides reliable, hands-free lighting that adapts to your daily routine.
