Soil Sensor Readings

This dataset contains historical readings for soil sensors within parks across the City of Melbourne. The sensors take a variety of readings such as salinity, temperature and moisture. The units and readings are included within the data. This dataset can be joined to the <a href='https://data.melbourne.vic.gov.au/Environment/Soil-Sensor-Locations/dxvp-runr'>soil sensor locations</a> dataset using the site id column. This dataset contains a large number of records, to download only a particular sensor's readings see our attached <a href='https://data.melbourne.vic.gov.au/stories/s/Guide-How-to-Filter-Datasets/ii52-k2da' target='_blank'>guide on how to filter data</a>.

<b>Different readings taken (based on unit column):</b>

  • <strong>%VWC: Volumetric water content</strong> is a numerical measure of soil moisture. It is simply the ratio of water volume to soil volume.

  • <b>ºC: Temperature</b> in degrees celsius.

  • <b>µS/cm: Salinity</b> is the measure of the concentration of dissolved (soluble) salts in water from all sources. (microseimens per centimetre)

Note this dataset may not contain a reading for every sensor for every hour as the sensor devices might not have a reading for each value. There may be situations where no readings are reported for all sensors or only some readings are reported at a particular site.

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 \"melbourne-vic-gov-au/soil-sensor-readings-mv4n-8k4v\".\"soil_sensor_readings\"
    LIMIT 100 
"}
EOF

See the Splitgraph documentation for more information.
