TPB #84 – Weather Proof Motion Sensor

Posted by:

I show how to make a weather proof motion sensor for the Camera Axe. Most of the video is about how the case is made, but I also touch on the fact that this sensor is more accurate than the standard Camera Axe motion sensor because it uses I2C instead of analog values to report distance.


Code (5.5 or newer an you must enable max sonar menu)

Part List:
* Sonar
* Case
* 3.5 mm plugs
* Misc screws, nuts, aluminium plate, washers and 2 1K resistors
