All 50,000 sprinkler heads in the CU system are controlled by radio from a computer in a small room off Folsom Stadium. A weather station at Franklin Field constantly updates the computer, which changes water schedules based on temperature, rainfall, wind speed, and relative humidity.
Ryan Heiland closely follows weather forecasts, and tweaks the Toro 8000 system to pre-water in anticipation of heat waves. This raises soil moisture profiles so plants withstand heat stress better.
