WFD data setup instructions

The Wetting Front Detector (WFD) tells you how deep water moves into the soil during and shortly after irrigation. It also captures a soil water solution sample which can be extracted using a syringe.

WFD's are often installed in pairs at different depths and are always associated with a Chameloen Sensor Array.

Add a WFD to a Sensor Array

  3. Select how many WFD's are installed (one or two).
  4. Enter the depth each is buried to.
  5. Click 'Update'.

You are now ready to enter data collected from your WFD.
