Product Introduction
When there is a certain amount of water vapor on the leaves, they are easily infected by some fungal and bacterial diseases. The RY-CYM/485 foliar temperature and humidity sensor can detect the presence and duration of humidity on the leaves, allowing researchers or producers to predict the occurrence of diseases and take relevant protective measures for plants or crops.

The RY-CYM/485 leaf temperature and humidity sensor can accurately measure leaf moisture and detect 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 changes in the dielectric constant of the upper surface of the blade medium. Low power consumption, capable of long-term uninterrupted monitoring. It is easy to install and can be hung on the greenhouse or on the mast of the weather station.
