Ambiquality Wiki

Ambiquality is an open-data platform for Indoor Environmental Quality (IEQ) monitoring. Sensors deployed in rooms report measurements of indoor environmental parameters — CO₂, temperature, relative humidity, particulate matter, VOCs, sound pressure level and illuminance — and the platform republishes them as linked open data under CC BY 4.0.

It was built as a bachelor thesis at the Prague University of Economics and Business (VŠE), author Vilém Charwot.

Who this wiki is for

• Sensor operators — people who have registered a building, room and sensor in the admin app and now need to make their device send data. Start with Sending measurements.
• Data consumers / developers — see how the data is published (observations API, DCAT-AP catalog, monthly archives).

The data flow in one paragraph

You register a building → room → sensor in the operator app and receive a one-time sensor key. Your device then POSTs batches of readings to the Ingestion API, which validates each reading and durably enqueues it. A background worker writes the accepted measurements to the time-series store, and the Public API republishes them as JSON, JSON-LD and CSV, plus a DCAT-AP 3.0 catalogue and monthly downloadable archives.

Measurements are immutable. Once published, a measurement is never silently changed or deleted — a bad reading can only be flagged as invalid. Send carefully.
