Electric Fence Monitoring System

A client came to us asking for help detecting when their electric fence was shorting out. They wanted to fix the issue before the cows found out. We designed a system to monitor the voltage on the fence and text the farmer if it’s too low. With several nodes on the fence, they network together and give an approximate location of the issue.

Below is a screenshot of a test I did to see how long the batteries last, and verify that the mesh network remains stable after extended usage.
