IoT Vibration & Temperature Sensor Prototype for Predictive HVAC Motor Maintenance

This system delivered predictive maintenance for HVAC equipment through an IoT pipeline. Using Advantech WISE-2410 vibration/temperature/humidity sensors and Milesight CT305 current transformers, data was transmitted through LoRaWAN US915 to a Milesight UG65 gateway. A lightweight control layer is attached to MQTT topics (http for testing) and evaluates signals against ISO-10816 vibration thresholds and motor current baselines, and classifies emerging faults before failure happens. Detected anomalies generate maintenance tickets surfaced through a web dashboard and a fault ticket tracker. The system is also capable of being extended into existing building management systems.
