IoT Sensor Telemetry (Synthetic) (Free Sample)
This is a free sample with 5,003 rows. The full dataset has 50,006 rows across 3 tables.
High-frequency telemetry from a simulated smart factory operating three CNC lines, a finishing cell, and a predictive-maintenance program over six months. Covers temperature, humidity, pressure, and vibration sensors sampled on a rolling 5-minute schedule with realistic shift patterns, machine assignments, maintenance alerts, and operational state changes.
Includes two injected anomalies: a progressive calibration drift on sensor 3 during month 4 and a sudden spike pattern on sensor 1 that signals an equipment failure event. Useful for time-series analytics, anomaly detection, edge telemetry pipelines, and Industry 4.0 monitoring demos.
