At the second annual BERC Cleanweb Hackathon, a Berkeley Lab Environmental Energy Technologies Division team consisting of Anna Liao, Daniel Olsen, and Andrew Weber, along with Robert Sadler from InTech Energy, took the top prize for best app by developing an intelligent residential irrigation system based on open source hardware. The app processes weekly weather, drought, and sunrise time data to set optimal watering schedules for automated sprinkler systems.
Each sprinkler 'client' is controlled by a server that handles all data processing and control decisions. The same signal can control an unlimited number of sprinkler 'clients.' The system developed by the team is projected to save between 3,000 and 6,000 gallons of water annually per residence depending on the type of system replaced and lawn/garden size.
The Cleanweb Hackathon, organized by the Berkeley Energy & Resources Collaborative encourages teams to build software-based business solutions and open-source code by introducing talented hackers at the University of California, Berkeley, to today’s energy and resource challenges.
