Wireless Soil-Moisture Sensors for Irrigation Control

Sensor-based controllers use on-site sensors, such as those that detect moisture, to determine whether the landscape requires irrigation. Researchers from the Pacific Northwest National Laboratory (PNNL) found that the sensor-based controllers can determine water needs for specific zones and thereby deliver only as much water as is needed to keep vegetation healthy.
