Sistema de monitoramento remoto do nível de caixas d’água empregando a tecnologia LoraWAN

Abstract

This work presents the development of a device used to measure the water level on water tanks. The device has low power consumption and is composed by ESP32 micro controller and LoRa radio powered by alkaline batteries and communication by LoRaWAN protocol that is an alternative to low power consumption and low data transfer applications. The display of measure results is given through application for mobile devices developed with the Javascript React Native library based on Android and iOS. The hardware built is micro controlled and the data obtained due to ultrasonic sensor to measure the level of the tanks. Batteries with over two-year autonomy and long-range transceiver LoRa for data sending. LoRa gateways are used and concentrator for receiving and data processing by TTN (The Things Network) community. The backend was developed on .NET which is an open-source platform using C# language. The application was hosted by Microsoft Azure, a cloud-based service. The device proposes an easy installation with low maintenance required providing the customers to consult their tank level in an easy and safe way because the tanks are usually placed on a hard-to-reach location.
