Search OpenSenseMap crowdsourced environmental sensor stations by location, name, group tag, exposure type, or measured phenomenon. Returns up to 100 stations with their sensors and latest measurement values. OpenSenseMap hosts 15,000+ community-operated senseBox stations worldwide measuring PM2.5, temperature, humidity, UV, pressure, CO₂, and more. Location search: provide latitude+longitude to find stations within max_distance meters (default 5 km). Name search: pass name to filter by station name substring (e.g. "berlin", "school"). Phenomenon filter: use "Temperatur", "PM2.5", "rel. Luftfeuchte", "Luftdruck", or "UV-Intensität" to find stations measuring a specific sensor type. Exposure filter: "outdoor" for weather/air-quality monitors, "indoor" for home sensors. Each result includes station ID (use with box_detail or sensors_latest), coordinates, sensor list, and last measurement values. Data is PDDL 1.0 public domain, no attribution required.
