What should I enter as the depth of the sensor at the time of activation?

If not desired differently, or not stated otherwise: place the sensors at 14 cm (5.5 inches) depth.

To place the sensor at the desired depth, keep an eye on the marks you can see on the sensor (see figure 6). You will be able to enter the amount of marks still visible after planting the sensor in our system, this way the system knows how deep the sensor was dug in. If you know the required depth and want to calculate the number of marks that must be visible for the respective depths, see figure below.

The calculated depth is measured from the center of the watermark sensor to each mark on the shaft of the housing.

Example: If you intend to place the middle of the watermark sensor at 14 cm deth/5.5 inch you need to make sure that the top mark is at soil level (0 visible marks above soil level). If your intention is to place the middle of the sensor at 6.5cm depth (minimal depth) the first mark should be at soil level and 5 additional marks should be visible.
