Leaf Wetness Sensor (LWS)

Capabilities

The LWS measures the presence of water or ice on its surface to simulate leaf wetness. It uses a dielectric measurement method on the sensor's upper surface, detecting even small amounts of moisture without requiring painting or complex calibration. Because it registers ice as well as water, the LWS feeds orchard frost detection and the broader agricultural weather monitoring WWG runs for growers.
