Industrial challenge / problem:
Unexpected bearing failures and overheating in electric motors cause unplanned downtime and operating losses.
Technical solution developed:
An embedded IoT sensor node mounted on the motor housing. The ESP32 samples acceleration data for RMS vibration-severity calculations according to ISO 10816 and sends an alert to SCADA.
Project component list:
- ESP32-WROOM-32
- MPU6050 accelerometer module
- MAX31855 SPI amplifier + Type K thermocouple
- IP65 aluminium enclosure
Expected result in operation:
Early detection of mechanical anomalies and automatic alarms when limits are exceeded.
