Irrigation第 16 / 100 题
A smart irrigation controller that adjusts run times using local weather data is called what?
a.A manual timer
b.An anti-siphon valve
c.A pressure regulator
d.An ET-based or weather-based controller
解析
An evapotranspiration (ET) or weather-based controller uses temperature, humidity, wind, and solar data to estimate plant water needs and adjust schedules automatically. This reduces overwatering compared with a fixed manual timer. MWELO encourages such controllers to improve landscape water efficiency.
