TUCSON, Ariz.—After Rain Bird introduced the ESP-SMT smart control system in 2009, the weather-based, 13-station controller quickly made a name for itself as a technologically advanced, water-efficient way to schedule irrigation. Now, Rain Bird is introducing the ESP-SMTe—an enhanced version of the original ESP-SMT that features numerous enhancements and the ability to manage up to 22 zones.
Like its predecessor, the ESP-SMTe consists of two key components—a controller chassis with an integrated smart panel and an on-site weather station that includes a temperature sensor with an integrated solar shield and a unique tipping rain bucket for instantaneous rainfall measurement. An intuitive on-screen wizard prompts users for site-specific and zone-specific information to create a customized, optimum irrigation schedule. The ESP-SMTe also combines historical data along with actual temperature and rainfall data to determine how much water is needed to maintain the optimum level of moisture in the soil. Each day, the controller uses all this information to decide whether to continue with its pre-defined irrigation schedule, suspend irrigation or adjust the schedule to apply more or less water as needed.
