The leaf surface humidity sensor is a plant surface humidity measuring instrument widely used in greenhouses, laboratories, farms, artificial climate rooms and other environments. The instrument is small in size, stable in performance and high in sensitivity. It adopts analog form and accurate measurement and is deeply loved by researchers in modern agricultural research. Foliar humidity sensor is an important basis for accelerating the development of precision agriculture. Using the instrument can understand the growth and development of crops as well as carry out crop growth research; prevent the occurrence of pests and diseases and early warning; foliar fertilizer, spraying, spraying and irrigation control, etc. To study the humidity of foliage, prevent pests and diseases, and spray sprinkler control important tools, how does the leaf surface humidity sensor accurately measure it? What is the working principle of the foliar humidity sensor? From the composition point of view, the leaf surface humidity sensor is mainly composed of a leaf surface simulation board, a signal processing circuit, a temperature correction circuit, a potting shell and the like. During the measurement process, its internal processor measures the entire leaf panel as a dielectric constant medium, and the humidity information is measured by the high-frequency signal source and its processing circuit. At the same time, in order to prevent the effects of temperature and drift, internal temperature correction and signal drift compensation circuits are also used to achieve accurate and reliable measurements. The above is the working principle of the leaf surface humidity sensor. It is worth mentioning that the leaf surface humidity sensor belongs to a very precise device. Therefore, users need to pay attention in some areas during use. For example, in the process of use, please do not disassemble it yourself. Use sharp objects or corrosion. The liquid contact sensor indicates that, in order not to damage the product, do not arbitrarily change the components or guides that have already been welded at the time of delivery to ensure the stability and accuracy of the use of the leaf surface humidity sensor.
