Product Type: Motion Detector,Hidden models Scope of application: indoor use only Package Included 1x infrared motion sensor 2x screws 1x instruction manual Review: Works a treat - Bought this for our bathroom so the kids don't have to worry about reaching the light switch, and it's been a great little upgrade so far. Installation was straightforward and the sensor picks up movement reliably when entering the room. I like that it gives you different operating modes, so you can set it up to suit your needs rather than having the light on all the time. It's made life a bit easier for the children and saves the usual reminders about turning lights off. Only had it installed for a short time, but so far it's working exactly as expected and I'm very happy with the purchase. Review: Very good - Very good. Mounted on the ceiling of our downstairs loo which is a small 1m x 2m room. The PIR picks up as soon as you walk into the room when dark, and the time delay switch’s off. Also no neutral required. ## Features - ✅ 【2-Wire Technology Infrared motion detector】No Neutral Required,2-Wire operation is reliable, energy-efficient, and cost-effective.Automatic motion sensor switch based on infrared PIR technology. Very easy to install and calibrate.Just by pressing button to adjust delay-time and light sensor, don’t need to open the cover and adjust the value with a screwdriver, this save you the hassle. - ✅【Power range】Whether it is low power or high power, motion detectors are perfectly compatible.
