Flood Monitoring System Using the Internet of Things

This paper discusses the problem of untimely notification of flood situations in the region and proposes a project of a system for measuring water levels in reservoirs in order to monitor these situations. The system includes several components: a device for water level measurement based on ultrasonic sensors, a module for data reception and transmission that takes into account areas without GSM signal using RF modules, a hardware-software complex for data transmission using cloud technologies, a web page, and a script for reading and processing information from the database. In this paper, the schematics of all the hardware part of the system were developed as well as programs were written for the microcontrollers of the respective components, including the website for data display. The results of testing the prototype with the implementation of the main functions of the system are also presented.
