Abstract: The multi-sensor applications will be combined to design and implement a smart agricultural management system based on the Internet of Things. The system collects real-time environmental parameters such as surrounding temperature, soil temperature and humidity, soil trace elements, carbon dioxide concentration, and solar light quantum in a multi-point layout, and uses multi-source data information to scientifically guide agricultural production entities. Research the content of multi-sensor information fusion, data information processing methods, automatic control effects and multi-scale environmental control in the network, real-time monitoring of comprehensive agricultural ecological information, realize accurate automation, information and intelligent control of crops, and effectively improve agricultural production efficiency.

Key words: embedded systems, precision agriculture, intelligent management, information fusion
