Design and Implementation of Marine Temperature Measurement System Based on LoRa

In order to improve the convenience of ocean temperature measurement and raise awareness of the marine environment, a design scheme of ship-based temperature measurement system based on LoRa was proposed. The characteristics such as low power consumption, low cost, longdistance transmission and so on of LoRa technology can meet the design requirements of data transmission. The system design idea was introduced, and the design of the temperature measurement node was focused on. The STM32f0 microcontroller and SX1278 chip were used as the core of the hardware. The hardware and software design ideas were briefly introduced. The communication distance and temperature acquisition of the system were tested. The results show that the system has the characteristics of stable working performance, long communication distance, high real-time performance, and can be widely applied to various temperature data collection system.
