Sistema IoT de Monitoramento do Nível da Água de Rios para Cidades Inteligentes

Abstract

Currently, heavy rains are the main causes of natural disasters in Brazil, causing rivers to overflow and disturbances for the community affected by this problem. Therefore, the prototype of a low-cost device was developed, whose main objective is to monitor and transmit the data obtained (volume of the water level of the rivers). Considering the transmission and analysis of data, the device is enabled in the concept of Smart Cities and Internet of Things, as it uses information technology to collect, analyze and transmit data. For the construction of the prototype, an Arduino microcontroller board and some other electronic components were used. The source code of the device was developed through Arduino IDE, a code compiler, based on the C / C ++ programming language, where the data received by the hardware will be interpreted and analyzed. An accuracy test was applied to identify and relate the values obtained by the device, where the results were satisfactory, considering that the distance data captured by the device were accurate, compared to the actual physical quantity. A simulation was carried out in a cylindrical container (where such a scenario can be made a relationship with a river), where the results reached the expected goals: using the developed code, calculate the distance between the water level and the device, interpret the calculated value and turn on the LED related to the water level situation (red LED for high level, yellow LED for medium level or green LED for low level). Given this result, it is possible to validate the functionality of the developed code and the built hardware.
