Research on Intelligent Agricultural Meteorological Information Monitoring and Alarm System

Smart agriculture is the integration and development of modern science and technology in agriculture related fields. Traditional agriculture is gradually transitioning to automatic and intelligent agriculture. Agricultural Internet of things can not only increase crop output, but also liberate productivity and improve labor return. Therefore, this paper studies the intelligent agrometeorological information monitoring system, which can wirelessly monitor the value and range of temperature and humidity, light, soil humidity, CO

concentration, and save manpower and material resources for people to monitor agrometeorological information at all time. The intelligent agricultural meteorological information monitoring system uses ZigBee technology conforming to IEEE 802.15.4 standard to deploy wireless networks and each node in the network communicates with each other, The terminal sensor sends the collected temperature and humidity, illumination, soil humidity and CO

concentration signals to the nearest routing node. The routing node wirelessly sends various signals to the coordinator, which then uploads them to the PC through the serial port. The PC displays all information and gives an alarm according to the designed limit value. This paper focuses on the analysis of the main framework and key technologies of the intelligent agriculture remote monitoring system, and the system research, design and implementation.
