  • very good sensor, works very well with raspberry pi

    posted by zhuyi

    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.
  • 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.
  • Two-Wire System Wall Mount Automatic Inductive Swi

    The device is very useful for use in corridors, hallways, stairways, utility rooms. Use in the pantry. Device is triggered precisely and quickly. Angles of actuation rather broad. When you are in the area of the device and moving, load shedding does not occur (which is very useful if you need to be lit room more than a minute)
    I consider it necessary to replace the rear side of the enclosure to the round (that would be freely entered into the mounting electrical box in the wall)

  • Well

    posted by bronepoezd

    Checked. Works.Has been ordered for installation in storage room, until set, but I think that'll do it the other day.The description of the goods is not poring over, and was pleasantly surprised to find that in addition to the motion sensor, there is also a light sensor. Afternoon light will not burn in vain.
    With purchasing it is happy. I plan to order still.
  • Great, but has no status information

    posted by PauliusB

    It is very easy to use and it works exactly as described. From system engineering point of view, it is constructed really well. MIC is very sensitive and broadcasts voice clearly.
    It could have some kind of status information. For example it could tell battery charge level over SMS. Or at least to send a SMS after turning security on or off.
    Great and cheap GSM PIR security system
