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.
