Interactive visualization of IoT power quality data on mobile devices

Ensuring the good health of industry operations is crucial as they are pushing themselves to have fully automated production. The mass adoption and rapid advancement of mobile devices has shifted the way in which businesses and consumers interact. Data visualization is an important method for big-data analytics, particularly to help human to comprehend and find pattern or trends. An Internet of Things (IoT) solution together with an adequate mobile application for proper data visualization would be extremely beneficial for the management of the facility and thus ensure continuous business operations. This paper describes an application for voltage sag visualization based on data monitored by an IoT PQ sensor. The sensor uses the ESP32 microcontroller to send data to the IoT platform monitored by an energy metering integrated circuit ADE9000. Through the new developed Android smartphone application, PQ data can be remotely accessed from remote smart phones, tablets or similar. The application uses Unity software. The paper shows measurements from voltage dips.
