  • Motion detection not great

    posted by alteredworld

    - Lights up when motion is detected while in the dark, but does not light up in a bright room.- LED lights saves battery.- 3 modes, auto, on or off. E.g. usable as night light or reading light.
    No batteries were included, but should be according to package. Requires 3 x 1,5 V (AA) batteries.
    Design is ok, but could be better.
  • very good sensor, works very well with raspberry pi

    somewhat low cost, couldn't get the cheaper one from DX, had to order this.package is as usual DX standard. Very easy to understand the connections, +5V, Ground, signal out, can adjust the holding time and sensitivity. Detect distance is pretty good, tried at least 7-10 meters, no problem.
    This is a very good sensor for DIY project, I believe it's a standard template design, since the layout is the same as rest of the similar products all over the web.
    worth to buy, highly recommended.
  • good product

    You can connect any lamp with E27 socket up to 60W (incandescent) and 20W (low power).When I install it just stayed light on and that happened because he had put the maximum time to adjust, so that we can take it as a pros as it has the option to keep the light on if necessary
    I tried to disarm it in case it was necessary to change any parts and is very easy
    In short ... if you buy it you will be very pleased with this product.
  • A 21st Century Lightbulb

    posted by DendoRacing

    Easily automates the lights in your house. Sensitivity is good with a decent angle and range. Includes a light sensor so the lights do not come on during the day. Stylish design that looks better than a normal light bulb.
    Finally the light bulb has entered the 21st century. We have a multi-story house with many stairs and corridors. By installing these light bulbs I am able to safely walk from top to bottom without touching a light switch.
    A modern and stylish light bulb that will automate your house.
  • Light sensors works great; easy installation

    The device easily detects motions in its working range. The schematics on the device is very useful, though there is no instruction in English.
    Manufacturer would do a great job if the back of the device was covered by an insulating material.Also, there is no way to attach the device to the wall of ceiling. I managed to do it on the plastic ceiling by attaching it to a special bulb socket that was lacking a bulb.
    Although it's not perfect I highly recommend it to anyone, because it's very useful.
