Sensor Data Generator

Industrial context: All data generation runs entirely in your browser — nothing is sent to any server. Use this tool to produce realistic time-series CSV files for testing IIoT dashboards, SCADA historian imports, ML training datasets, and OEE calculations. Sine waves model periodic processes (temperature, pressure cycles), sawtooth/triangle waves model PLC analog I/O ramps and linearization tests, square waves model digital on/off signals, ramp trends model warm-up or fill sequences, and random walk with noise simulates real sensor jitter on physical processes. Use the cycles control on periodic waveforms to set how many complete oscillations occur over the dataset. Generated files are standard RFC-4180 CSV with configurable timestamp formats for direct import into Historians, PI System, Ignition, or PLC simulators.
