Sensors are arranged in each node, and the measured results are packaged in a certain format and sent to the coordinator node through WiFi network. testEquipment: 7 sensor nodes, access to the Internet. Through the system setting, one of the nodes is used as the sensor node to send the collected data according to a certain periodOne node is used as gateway node to complete data aggregation function; Two nodes are used as routing nodes to complete the routing function; The other four nodes are used as sensor nodesPoint to complete the data acquisition function.Test method: all the sensor nodes are placed in a certain area of the simulated orchard environment, and two of the sensor nodes can be placed in the gateway nodeWithin the scope of direct communication, the other two sensor nodes are far away from the network management node, so they can not communicate directly, but need to be transmitted through routing to achieve communicationAfter the process configuration is completed, the sensor node is turned on, and the sensor node is used for networking communication, and the data can be viewed
