Air Quality

Air quality data collected every 5 minutes via a network of sensors deployed throughout the city. The devices record particulate matter (PM2.5), temperature and humidity. Although you can develop an application using this data, we recommend you use the real time API located at: https://winnipeg-aq-sta.sensorup.com/v1.0 (Developer documentation here http://developers.sensorup.com/docs/) as this data is collected for historical purposes.

Querying over HTTP

Splitgraph serves as an HTTP API that lets you run SQL queries directly on this data to power Web applications. For example:

curl https://data.splitgraph.com/sql/query/ddn \
    -H "Content-Type: application/json" \
    -d@-<<EOF
{"sql": "
    SELECT *
    FROM \"winnipeg-ca/air-quality-f58p-2ju3\".\"air_quality\"
    LIMIT 100 
"}
EOF

See the Splitgraph documentation for more information.
