Aplicação de internet das coisas no monitoramento de corrente, tensão e temperatura em motor de indução trifásico

Abstract

The Internet of Things (IoT) can be defined as the connection between the physical and the digital world, that is, a global network between everyday, personal or industrial objects that have embedded technology capable of collecting, transmitting and make database-based decisions. The proposed work aims to develop and implement a low cost acquisition system, following industry trends 4.0, which is inserting IoT in industrial environments. Using ESP32 microcontrollers from Espressif Systems to monitor overcurrent, overvoltage and high temperature of the three-phase induction motor. Electrical quantities are acquired by the Voltage and Current Signal Acquisition and Conditioning Module. The temperature is supervised by an internal engine temperature sensor. This data is read, processed and transmitted by two ESP32, and by applying IoT technology the overcurrent, overvoltage and high temperature values are clouded. Data is made available for viewing in graph form on the ThingSpeak platform and alarms are triggered for registered users' smartphones via the Telegram application.
