  • 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.
  • Cheap but excellent

    Cheap but works as well as the expensive PIRs I have at my house.
    I have bought 2 of these now to add to the existing PIRs on my alarm system. Seems to sense movement very well but not prone to false trigger. It came with only Chinese instructions but it was easy to find a detailed English pdf manual on the web for the same model.
    I would recommend this to anybody.
  • Excellent and chep PIr detector for interior.

    Excellent and economical for alarm PIR detector operating at 315 Mhz. Very easy to install and has a great scope. There is nothing to code if it will be detected automaticly by the central alarm. Quality of construction is very nice.It comes with a plastic to hauling in to the wall and calibrate the orientation through the space.
    Nothing to say about it.
    Excellent for wireless alarm cental system. I recommended it to buy!
  • A nice product
