Leaf Wetness Sensor

 

Product overview
The leaf surface humidity sensor has stable performance and high sensitivity. It is an important tool for observing and studying leaf surface humidity, preventing diseases and pests, and spraying irrigation control. The leaf surface humidity sensor can accurately measure the leaf surface humidity and monitor the trace moisture or ice crystal residue on the leaf surface.
The sensor measures the presence of fog, water vapor or ice by simulating the change of the dielectric constant of the upper surface of the blade medium. Unlike sensors based on resistance measurement, it does not require coloring or calibration, but also provides effective monitoring of ice. Low power consumption and long-term continuous monitoring.

Functional features
Small appearance and volume design, easy installation
Simulate the structure design of the blade surface, so that the sensor can truly reflect the water loss process of the blade surface.
It can detect fog, ice, condensation and rainfall.
Waterproof and sealed, it can be directly applied to foliar fertilization, spraying and sprinkler irrigation, and can be used outdoors.
High precision, fast response, good interchangeability and reliable performance.
Stable performance, fast response, low power consumption and strong anti-interference ability

working principle
The leaf surface humidity sensor adopts the principle of resistance measurement. It is composed of external sensing grid and signal transmitter. When in use, the sensor device is placed near the plant leaves, and the sensor will imitate the process of obtaining water from the plant leaves. The leaf surface humidity sensor adopts a width sensitive electronic induction coil, which can test the plant leaf surface humidity data with high precision.
