Watch the signal
S1 teal · S2 orange · S3 violet. Dashed line: warning at 70°C; clears at 65°C.
A SMALL SIGNAL, BEFORE A BIG PROBLEM
Pump Signals.
Follow three temperature sensors through a warming event, a missing-data interval, and recovery.
Synthetic replay. These are generated readings and rule-based alerts, not real equipment data or a trained failure-prediction model.
Event trail
A missing sample never becomes a zero reading. Repeated hot samples produce one warning until recovery.
How this works
A seeded Python generator produces 353 readings. SQLite stores readings and alert transitions. The hosted demo replays an exported snapshot; the downloadable source also runs a local read-only API.
At 70°C a warning opens. At 65°C it clears, preventing alert chatter. A gap event records missing intervals when a sensor returns.
This companion demo makes the monitoring pipeline inspectable without Raspberry Pi hardware. It does not reproduce the original project's Random Forest model.
