openSenseMap

API

Free API for hyper-local weather data from citizen science senseBox stations

Overview

The openSenseMap API provides access to real-time and historical environmental data from global personal weather stations (senseBoxes). Key endpoints include /boxes (list stations with metadata), /boxes/{id}/data (fetch measurements like temperature, humidity, and air quality), and /stats (aggregated data insights). Responses are JSON-formatted. Use cases include building custom weather dashboards, integrating hyper-local data into apps, conducting citizen science research, or educational projects analyzing local climate patterns.

Example Integration (JavaScript)

script.js JS


fetch('https://api.opensensemap.org/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
