Research on distributed agricultural environment monitoring system based on LoRa technology

In order to solve the problems of complex networking and short transmission distance in ZigBee network agricultural monitoring system, this paper proposes a distributed agricultural environment monitoring system based on LoRa technology. The LoRa network is used to realize the system perception layer design. Based on the simple star networking architecture, the low-power wide-area Internet of Things intelligent agriculture system is constructed. The network architecture, LoRa node and LoRa base station software and hardware design and communication protocol are described. Through the analysis of the experimental test results, the scheme has the advantages of simple networking, wide coverage, high reliability of data transmission, low power consumption and long working cycle, which is very suitable for the promotion and application of complex agricultural production site.
