ZLW-2 Leaf Wetness Sensor

ZLW-2 leaf wetness sensor is of high sensitivity, an important tool to observe and study the leaf moisture, prevent diseases and insect pests, as well as spray irrigation control.

The leaf wetness sensor can accurately measure the humidity of the leaf surface, and can monitor the trace water or ice crystals on the leaf surface. The shape of the sensor is simulated by the design of the blade, and the characteristic of the leaf surface can be more accurately reflected in the leaf environment. It measures the presence of fog, moisture, or ice by the change of dielectric constant of the upper leaf surface.

Leaf Wetness Sensor FAQs

what is a Leaf Wetness Sensor?

The Leaf Wetness Sensor (LWS) detects leaf wetness and ice formation in plant canopies. The LWS is used to predict when to spray crops, quantify water storage, and monitor crops for foliar diseases including rust and blight.
