Hydrascout Placement

Find the most representative spots in a field to install Hydrascout soil & temperature sensors.

What do you want to do?

Your installed probes

Type the Digital Matter serial of each probe (several at once, separated by commas or spaces). The app reads each device's last GPS position from HSTI Logger Overview (log in there if asked) and puts it on the map.

    No GPS on a device? Place it by hand, or import a CSV (lat, lon columns), GPX, KML or GeoJSON file. Drag a probe on the map to correct its position.

    Find the field

      Your irrigation blocks

      A block is a part of the farm watered on its own (one valve or one sector). HSTI recommends one probe per block. Not sure? Leave it empty, draw the whole field under “Draw the blocks” and the app suggests a number from its size.

      Draw the blocks

        No field yet.

        Press Draw borders on a block, tap its corners on the map, then Finish. The blocks together are the field: crop vigour, soil and the probe spots all use them. You can also import them from a GeoJSON or KML file (one polygon per block, e.g. from your farm software or Google Earth).

        Crop vigour and soil

        The spots use the date shown.

        Recommended. The app searches free Sentinel-2 images (10 m) of the last 14 months, skips cloudy ones and picks the clearest image with full crop cover. Use the timeline to see how the field changes through the season. You can also upload your own NDVI map from a drone.

        SoilGrids 250 m maps, shown only inside your blocks (or the whole field) once they are drawn. They show regional patterns, so expect only a few cells over one field. The key is on the map; tap the map to see the soil type and texture at a spot, even with the soil map off. For the detailed French soil map, open the carte des sols on cartes.gouv.fr and click the field.

        Sensor spotsCheck the positions

        No block map? Pick the number of irrigation blocks here: one probe per block.

        The app works out where probes should go in each block, then compares each installed probe with it: inside a block, far enough from its border, and at a point typical of the block.

        Recommended spots

        Drag a numbered pin on the map to adjust a spot (an obstacle, a drain, an access path). Its notes, the report and the exports follow the new position.

            Return on investment

            A Hydrascout probe typically saves 10–30% of irrigation water, and the pumping hours, electricity or diesel that go with it. Ask the farmer for their own figures: the closer they are, the more convincing the result.
