Soil water potential detector |
摘要 |
The present invention related to a water detector for use in determining the presence of sufficient water in irrigation systems and plant cultures in general. The detector includes a probe and the presence of water in a soil induces modifications in the optical properties of the probe. The optical properties are monitored and used to control the activation or deactivation of the irrigation system, emit a warning signal or provide a reference value of water potential for monitoring purposes.
