A telemetry stream: timestamped readings from forty devices with temperature, humidity, battery level and status. The shape of every time-series ingestion and downsampling demo.
The small files are static downloads. The large ones are generated in your browser from the same fixed seed, so every copy of sensors-100000.csv on earth is byte-identical — reproducible test data with no 60 MB download.

Timestamps advance monotonically (one reading per 30 seconds with jitter), so resampling, windowing and gap-detection demos behave like production telemetry.
A small share of readings are warning/error status with low battery — enough signal for alerting-logic demos.
Good for: Downsampling / moving-average demos · Time-window aggregation tests · Alert-threshold examples.
License: CC0 / public domain — use it anywhere, no attribution needed.
They advance ~30 seconds per row with a few seconds of jitter — monotonic enough for windowing demos, jittered enough to be realistic.
CC0 (public domain). Use it in tutorials, tests, courses, screenshots and products — no attribution required.
Yes — every size is generated from a fixed seed, so the same file is byte-identical for everyone, forever. Reproducible tests, stable teaching materials.
