overview

When there is a certain amount of water vapor on the leaves, they are easily infected by some fungal and bacterial diseases. Leaf surface humidity sensors can measure the presence and duration of humidity on leaves, allowing researchers or producers to predict the occurrence of diseases and take relevant protective measures for plants or crops.

Leaf moisture sensor (LWS) can accurately measure leaf moisture and monitor trace amounts of water or ice crystal residue on the leaf surface. The sensor adopts a blade like design to simulate the characteristics of the page, which can more accurately reflect the situation of the leaf environment. It measures the presence of water or ice by mimicking the change in the dielectric constant of the upper surface of the blade medium, which allows the sensor to detect the presence of water or ice at any position on the sensor surface. Unlike sensors based on resistance measurement, it does not require coloring or calibration, and can also provide effective monitoring of ice.

LWS has low power consumption and can perform long-term uninterrupted monitoring. It is easy to install and can be hung on the greenhouse or on the mast of the weather station.

Advantages and Characteristics

• Imitate the characteristics of leaves

• No need for paint or calibration of individual sensors

• Detecting trace amounts of water or ice on the surface of leaves
