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.

    No good use? I can think of many, Hope I can constuct this hack myself. Anyone willing to make some and sell to me?

  2. 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

  3. If you view the video at Gear Live. Skip forward to 33:15 and that is where the demo starts.

    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.

    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!

    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…….

    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…

    motion sensors are very useful when you want to detect stray animals or burglars on the move:*;
