3. SMART UPS WITH MICROCONTROLLER BASED MONITORING

Uninterruptible power supply (UPS) monitoring system using message queuing In a big infrastructure, telemetry transport protocol provides a solution to UPS monitoring problems. In this project, the IOT protocol for SMS conversations is used to demonstrate the minimal amount of message data. The system outlined in this project used a microcontroller that was WiFiconnected to the Internet of Things based on the DATA cloud concept. The system's communication protocol, graphical, was created with lightweig ht communication in mind. This arrangement was intended to display UPS monitoring data. UPS parameter could be monitored using a graphical application. There were some differences in data obtained from sensor with the measurement results of measuring instruments specified for each parameter: the difference of input voltage was equal to 0. 20%, while differences of output voltage, output power and output current reached 1.34%, 0.17% and 20%, respectively.
