Foliar humidity sensor principle and application range

At present, with the rapid development of facility agriculture, the goal of achieving precision agriculture has become the common pursuit of people in the agricultural field. In order to further improve the level of agricultural science and technology and promote the development of precision agriculture, in recent years, instruments such as leaf surface humidity sensors are The application in agriculture is more and more extensive. It provides scientific basis for the research of agricultural biology and the formulation of agricultural operations.
Foliar humidity sensors are one of many agricultural instruments currently used. Although they are applied to different types of biological research fields, they have one common feature: high technological content and high measurement accuracy. The leaf surface humidity sensor is mainly used for measuring the percentage of water content on the leaf surface of plants. It is a professional instrument for measuring the volumetric moisture content of the leaf surface of plants. In order to let everyone know better the working process and application of the leaf surface humidity sensor, let's briefly talk about the principle and application scope of the leaf surface humidity sensor.
1. The principle of the leaf surface humidity sensor The leaf surface humidity sensor adopts the principle of resistance measurement. It consists of a surface-sensing grid and a signal transmitter. When the sensor is used, the sensor is installed near the leaf of the plant under test, and the sensor will simulate the leaf of the plant to obtain water. process. The leaf-surface humidity sensor uses a width-sensitive electronic induction coil to test plant leaf surface humidity data with high accuracy.
2. Application range of the leaf surface humidity sensor The leaf surface humidity sensor is suitable for water-saving agricultural irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid measurement, plant cultivation, scientific experiments and other fields.
The above is the principle and application scope of the leaf surface humidity sensor. Although most of these plant physiological instruments are in the stage of biological research, they cannot be applied in a large area. However, from the experience of agricultural applications, most of the research is ultimately aimed at the application of laboratory research to agricultural production. Therefore, we believe that in the future, the technical level of detection instruments such as leaf surface humidity sensors will be even more High, the application will be more extensive, will greatly promote the fine production of agriculture, and ultimately achieve the ultimate goal of precision agriculture.
