Cleanroom Humidity Monitoring Dashboard

The default band is 30–60% RH typical for cleanrooms (process-specific — electronics often tighter and drier). Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.

There's no universal figure — it follows the process. Common ranges are 30–60% RH, but electronics/semiconductor areas often target a tight low band to control static and moisture-sensitive steps, while sterile pharmaceutical rooms set limits to suppress microbial growth and protect product. The governing documents are your URS, validation protocol and GMP/ISO 14644 framework. Monitor against your validated band, treat excursions as deviations with documented investigation, and remember humidity control interacts with the room's pressure cascade and temperature.

Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.

Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
