Using sensors to reduce wasted support time: case study for testing in IoT
summary
Pilot implements sensors (temperature, gyro, accelerometer) on a can-pressing line, maps 4–20 mA signals through a field coupler into an industrial gateway that publishes MQTT to cloud, with a dashboard for aggregated alerts. Goal is to cut support visits, but testing reveals concrete failures: missing field logging, reconnect logic fails after 30 minutes, brittle calibration and no remote re-provisioning, token-revocation gaps, GDPR risk from shift-pattern data. It's a working pilot that surfaces architecture and operational gaps rather than a finished product.
