Challenge! – Motion Sensor for Wildlife Protection
Motion Sensor for Wildlife Protection

The idea for this project is to build sensors to install near fences in order to create a monitored perimeter that could alert rangers of potential intrusion from poachers into the reservation. The sensors are meant to be compatible with one another, regardless of who built them, and be able connect in series with one another to take advantage of international crowd sourcing efforts.
The documentation for this project will consist in two sections. The first will be a basic prototype, easy to build and understand, which will provide a foundation to improve upon. Potentially, it can be used to introduce people with no experience intro building more complex project. The second part of the documentation will focus on improving the basic model into a field ready sensor, with better manufacturing techniques and increasing complexity.
Materials Needed – Basic Prototype
Arduino Micro $8.99
Ultrasonic Sensor $5.38 (Also sold for $1.43)
Small Breadboard and Jumpers $3.99
Piezoelectric Buzzzer $1.50
9V Battery $1.50
Note: Usually, the unit price for electronic components in bulk or packages is considerably cheaper. If you want to build more than one device it is recommended to look for better prices online.
