Design and Implementation of a LoRa-Based Multi-Terminal Communication System

With the rapid development of the Internet of Things (IoT) technology, there is an increasing demand for communication. Long Range (LoRa) communication, as an emerging wide-area network communication technology, has been widely used in many fields by virtue of its unique advantages of low power consumption and long distance. This paper describes the design and realization of LoRa -based data transmission system, which adopts microcontroller as the control core, LoRa module as the transmission core, and adopts a variety of data interfaces to collect sensor data and realize low power consumption through power control circuit. Perform overall testing of the completed design system. The results show that the system successfully realizes the data transmission between multiple terminal nodes and gateways while also providing the system with low-power sleep function.
