The pipeline
- Edge sensor. Particulate, microbial, pressure-differential and VOC probes sample at 1 Hz on signed firmware. Readings are cryptographically stamped at the source.
- Gateway. On-site gateways buffer, deduplicate and forward via TLS 1.3 to the nearest regional ingestion node. Local cache survives 72h of WAN outage.
- PollutecSense cloud. Time-series store with 7-year retention, anomaly detection calibrated per ISO 14644-1 cleanroom class, and immutable audit trails.
- Read-only API. REST + GraphQL endpoints, with CSV/JSON export and signed audit packets for regulators. No write access is exposed to tenants.
Data residency options: EU-West (Lyon), MENA (Dubai), LATAM (São Paulo). On-prem deployment available for sovereign hospital networks.
