Tiny wireless motion sensor

wireless motion

[Nate True] states several times that there isn’t any good use for this project, but his wireless motion sensor is still fun. The transmitter features a passive infrared motion sensor. It sends the output over the 433MHz band to the receiver module. The receiver has a small piezo that plays sounds based on the PIR’s output. His project is featured The Bleeding Edge 006.

  1. YES!!!! A simple proximity detector for my room.

    Im live in a corner of the basement and it is a long walk to my room. Now i can install one of these to know when my brother is comming and begin doing something so i can say im busy and have him leave me alone.

    Put one in your shed and then wire it up to an amp. Then inside your house have a speeker hooked up to the house for you suspicious types

  2. No good use? Tell that to The Smoking Man, who had one on the path to the cabbin he was hiding in! (epp. 5×20, i believe)

    Too nerdy?

    Ok.

  3. Hmm, nice idea tony! It wouldn’t be too hard to wire it in to a keyboard so that it “presses” alt-tab… Join me tony, together we can end productivity!

  4. Does the video give detailed instructions on it? Cause it will take me forever to DL (768 Kb DSL) and I don’t want to waste my time….

    -Thanks in advance
    P.S. Jeff if this video is detailed I’ll build you one…….

  5. Billy-
    It doesn’t show you any instructions on how to build one. it just demos the useage. i wish he put up a more indepth walkthrough. or just instructions, he just gives a partlist, and a general idea…
