Sensor.Community data: particulate matter PM 10 & 2.5, relative humidity and temperature.

The data from the Sensor.community is uploaded to a PostGIS database every hour. The API query returns the average of all measured sensor values from the last 5 minutes. If the request fails, the API is queried up to five more times at 5-minute intervals. Only the data from the last week is stored. The data offered for download is extracted as GeoJsSON at 1 am CEST.

Sensor.community所采集的数据每小时上传至PostGIS数据库。API查询返回过去五分钟内所有测量传感器值的平均值。若请求失败，API将在五分钟间隔内最多查询五次。仅存储最近一周的数据。提供的下载数据以GeoJSON格式在中央欧洲夏令时凌晨一点提取。
