How is the wetness of a leaf measured?

Leaf wetness sensor introduction: 

Leaf wetness sensor can measure the percentage of water content on the surface of plant leaves, using the principle of resistance measurement, it consists of surface sensing Gershon and the signal transmitter, when using the sensor will be installed near the measured plant leaves, the sensor will simulate the process of the plant leaves to obtain water.

How is the wetness of a leaf measured?

The leaf wetness sensor can accurately measure the leaf surface humidity, and can monitor the trace water or ice crystal residues on the leaf surface. The shape of the sensor is designed to mimic a leaf, which realistically simulates the characteristics of the page and therefore more accurately reflects the foliage environment. It measures the amount of water or ice present by mimicking the change in dielectric constant of the upper surface of the leaf medium. Low power consumption allows for long-term uninterrupted monitoring.

For leaf plants, when there is a certain amount of water vapor on the leaf surface, the leaf surface is easily infected by some fungal and bacterial diseases. leaf wetness sensor can measure the presence and duration of moisture on the leaf surface, so that the researcher or producer can predict the occurrence of diseases, and thus take relevant protective measures for the plant or crop.

Leaf wetness sensor role and value:

1. to understand the growth and development of crops as well as crop growth research.

2.Prevention of pests and diseases as well as early warning.

3. Foliar fertilization, spraying, misting and irrigation control. 

4. Simulate the foliage structure design, so that the sensor truly reflects the foliage water loss process.  

5. Detect fog, icing, dew and rainfall.

Leaf wetness sensor installation method:

1. leaf wetness sensor is easy to install, just place the sensor next to the crops or leaves, use non-metallic wire to pass through the small holes at the front of the leaf sensor, hang it on the branches and trunks of the tree through the line, and fix the device to the branches or stalks with the wire or line, that is, the installation is completed.

2. It can be hung on the greenhouse's trellis or the weather station's mast.

Typical applications of leaf wetness sensor mainly include water-saving agricultural irrigation, greenhouse greenhouse, flowers and vegetables, grass pasture, soil quick test, plant cultivation, scientific experiment and other fields, and through its outstanding application in these fields, it fully embodies the characteristics of science and technology serving agricultural production, and creates important conditions and research materials.
