Patented Rain Bird® RainWatch™ technology maximizes water efficiency, while minimizing system wear and tear, through intelligent, real-time decision-making based accurate rainfall measurement.

 

 

 

 

 

 

  • The industry’s first active rainfall monitoring and response system.
  • The only system designed to automatically react to rainfall and adjust sprinkler application rates to take full advantage of natural rain, thereby eliminating over‑watering.
  • Saves water and electricity, while keeping the course drier and more playable, by pausing, adjusting or canceling irrigation in the event of rainfall.
  • Results in reduced wear and tear on irrigation system components.
  • An integral part of Rain Bird Central Control Software versions 4.0 and higher.

 

How RainWatch Manages Rainfall

  • Stationed throughout the course, one to four high-resolution RainWatch rain cans collect environmental data.
  • A rotor can be set to react to any of the rain cans.
  • The central control system continuously polls each rain can.
  • Rainfall data received by the system is used to make intelligent decisions based on user-defined responses:
    • System Response: For course-wide reactions
    • Program Response: For program-specific responses
    • No-Action Response: For monitoring only
      • Intelligent responses include:
        • Pause
        • Resume
        • Adjust runtimes and resume
        • Cancel

 

An Example of RainWatch in Action

  • Your daily irrigation schedule calls for 0.20 inches (0.51 cm) of precipitation.
  • A storm begins and once accumulated rainfall reaches your desired 0.04-inch (0.10 cm) threshold, RainWatch suspends irrigation.
  • The storm passes after putting down 0.11 inches (0.28 cm) of rain.
  • Rain Bird software automatically adjusts remaining runtimes for active stations, as well as those stations yet to run.
  • Natural participation is seamlessly integrated into scheduled irrigation, resulting in a water savings of 0.11 inches (0.28 cm).
