Modular Animal Welfare Containment and Notification System
Team Website

The Gary and Jerri-Ann Jacobs High Tech High InvenTeam invented an electric fence system that can detect breakage and remotely notify the owner of the problem. Whenever a break or failure in the electric fence system is detected, the owner will receive a text notification to their mobile device detailing the failure and its specific location. Precise detection can reduce the time to repair the fence and recover loss of livestock. Owners can install modules at an increment of their choosing thus making the resolution of the failure analysis completely customizable. The system works well with fence energizers up to 20,000 volts with pulse-widths as small as 3 microseconds. Existing fence system can be retrofitted. The main system costs approximately $120 and each module costs approximately $9.
