Application of sensors in precision agriculture

To accelerate the pace of precision agriculture and broaden its application, it is quite important to develop multifunctional sensors with high efficient, stable and inexpensive features. This paper mainly summarized the working principles of new type sensors and their application in agriculture, such as biosensor, electronic tongue, electronic nose and machine vision, etc. And then, the particular demands of each agricultural stage for sensors also have been discussed, including production, processing, storage, transportation and distribution. Finally, the future direction of agricultural monitoring sensors was prospected.
