LWS-L Leaf-Wetness Sensor
The LWS, manufactured by METER Environment, can detect small amounts of water or ice on the sensor surface for leaf wetness applications. Because the LWS measures the dielectric constant of the sensor’s upper surface, it can detect the presence of water or ice anywhere on the sensor’s surface.
