Leaf wetness is an important indicator of the infection of pathogens on the leaves. The amount of moisture on the leaf surface makes it easy to be infected by fungal and bacterial diseases. The leaf wetness & temperature sensor can measure the presence and duration of the moisture and temperature on the leaf surface. Thus, it can provide information about wetness (from dew, rain, pesticide, and irrigation, etc.) and the temperature of the leaves. With these data available, farmers can make better decisions for irrigation, pest control, and other measures to make the plants and crops grow better.
