openSenseMap
Live readings from citizen-run senseBox weather stations
An open-data platform where hobbyist senseBox stations publish environmental measurements — temperature, humidity, particulate matter, UV and more. Fetch a single box to see its sensors and latest values, or query boxes by bounding box. Keyless and CORS-friendly.

Is openSenseMap free to use?
Yes — openSenseMap is a free weather API. Free tier: Free (open-source citizen-science platform). Whether the free tier allows commercial use is unclear — check the provider docs.
Does openSenseMap need an API key?
No — openSenseMap needs no API key or signup. You can call it straight away; rate limits still apply (Unpublished).
Can I call openSenseMap from the browser?

Is openSenseMap up right now?
As of our last scheduled check, openSenseMap is unmonitored. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
