Abstract

In response to the high concealment and difficulty in managing seawater intrusion, this article designs a seawater intrusion detection and early warning control system based on NB IoT, in order to achieve real-time detection of seawater intrusion and provide remote warning. The system mainly includes two aspects: hardware design and software programming. Among them, the hardware mainly consists of power module, microcontroller minimum system, TDS (conductivity) sensor module, water temperature sensor module, LCD module, NB IoT module, etc. On the basis of completing the system design, a sodium bicarbonate aqueous solution with the main solute is used, as well as a simulated seawater detection mixed with a certain amount of sodium chloride in a clear water solution. The test results show that when the TDS detection data of the system exceeds the program setting value, the warning function is triggered, and the buzzer generates a beep to start the alarm. The system has functions such as uploading measured data to the cloud platform for real-time display of detection data and viewing historical data, which has certain application value in practical applications.
