4XT-M
wireless growing media conditions sensor
Moisture measuring range
At three depth levels VWC (Volumetric Water Content) measurement: 0-100 %
The VWC at three depth levels is calculated in realtime based on preset calibration values or by a selflearning algorithm in which measured min-max values
are constantly included in the conversion to the VWC percentage.
The three zones, evenly distributed over the length of the legs, are used to calculate the capillary action and suctionforce of the substrate
To be used in pot sizes 17+, slabs and the open field.
The sensor operates completely independent immediately after being inserted into the soil. The device sends data via the worldwide Sigfox and various LoRa WANs. A real fully hybrid end solution.
