Industrial Motor Protection System Using IoT

Single-phase induction motors are essential in domestic and industrial applications due to their low cost and simple construction. However, they are highly vulnerable to electrical faults such as overvoltage, undervoltage, and overcurrent. This paper proposes an IoT-based system using an Arduino Uno and a PZEM-004T module to monitor electrical parameters including voltage, current, power, and frequency in real-time. The system features an automated protection mechanism that trips a relay when parameters exceed safe limits. Data is uploaded to the ThingSpeak IoT platform for remote monitoring. Experimental results show improved safety and reliability in motor operations.
