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.

TPB #6 – Motion Sensor

Posted by:

This episode shows how to use a motion/distance sensor with the Camera Axe.

The sensor used is a LV-MaxSonar-EZ1 (datasheet). This sensor not only detection motion, but will give back a distance from the sensor. It measures distances from 0 to 21 ft and take about 20 readings per second. 20 Hz is more than fast enough for wildlife. Check out the data sheet for more detailed information.

I show how ...
