Parameter to be measured:

Soil moisture, soil temperature, EC

Method:

Capacitance

Equipment:

  • 5TE Decagon
Effective range of temperature: -40°C - +50°C
Effective range of soil moisture: 0 - 60 % volumetric water content
Accuracy: ±3% without calibration, ±1% - ±2% with calibration
Dimensions: 145mm x 33mm x7 mm, three stripes

Advantages:

  • Relatively cheap
  • Easy to install
  • Compatible with many loggers

Disadvantages:

  • Calibration needed
  • Small measurement volume compared to other sensors

What to watch out for:

  • Careful installation, air gaps have a sustainable influence on the measurement compared to other sensors because of the small measurement volume
  • Probe is tenderly and will break, if it is pushed in resistive media.
