Leaf humidity, at first glance, you may think: leaf humidity does not seem to have anything to do with crop growth, but we have to look at it from a scientific point of view. Let me first give you a sense of how important the water on the leaves is for the growth of the crops. When the crop is photosynthesizing, it needs a lot of water to meet its photosynthesis intensity, so that it can make more nutrients and promote its growth and development. The content of foliar water also directly affects the intensity of transpiration of crops. Transpiration can promote the absorption of water by the roots of the crops, thereby promoting the metabolism of the overall cells of the crops and thus accelerating the growth of the crops.

However, in our actual planting production, we don't know the humidity of the leaves and their water content, so we can't effectively control the sprinkler irrigation system to dry the pages to increase the leaf surface humidity or open the ventilation system to lower the leaves. Surface humidity. Xinxin Electronic Technology Co., Ltd. has developed this type of leaf surface humidity sensor—— X8W850-H2 according to the particularity of leaf surface monitoring and the specific shape of leaf growth. The built-in module of the leaf surface humidity sensor adopts an original chip imported from the United States, which is composed of a surface-sensing Geshan and a signal transmitter, and uses the principle of resistance measurement to measure the percentage content of water on the surface of a plant leaf.

The sensor is simple and convenient to use. It only needs to be installed directly near the tested plant leaves. During the detection process, the sensor will simulate the process of obtaining water by the plant leaves, thereby measuring the moisture content of the leaves. In some fields, the sensor is also suitable for measuring the surface humidity of objects. X8W850-H2 is now widely used for measuring the surface humidity of plants or objects in greenhouses , laboratories, breeding, production environments, artificial climate rooms, etc.
