  • Internet-of-things based crop growth monitoring device and method thereof
    Patent number: 11073505
    Abstract: An Internet-of-Things-based crop growth monitoring device includes a plurality of monitoring mechanisms. Each monitoring mechanism includes a base and a support rod fixed on the base. The support rod is provided with an electric element installation casing formed by snap-fitting an upper conical cover and a lower conical cover. A component for driving a swing cantilever to rotate is provided on the support rod at a position near a lowermost surface of the upper conical cover. A plurality of distance measuring laser sensors are provided on the swing cantilever. A component for driving an ultra-high-definition camera to rotate is provided on the support rod at the section of the upper conical cover. The images captured by the ultra-high-definition camera is used to obtain the leaf growth situation of the crops, and the data collected by the distance measuring laser sensors is used to determine the plant height of the crops.
