Parameter to be measured:
Soil moisture
Method:
Capacitance
Equipment:
- HS10 Decagon
- Effective range of temperature: -40°C - +50°C
- Effective range of soil moisture: 0 - 57 % volumetric water content
- Accuracy: ±3% without calibration, ±1% - ±2% with calibration
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.
