Pivot mounted cosmic-ray neutron sensor for improved irrigation scheduling
Introducing a pivot mounted cosmic-ray neutron sensor (CRNS) for efficient irrigation scheduling, eliminating the need for seasonal probe removal. This innovative system provides integrated soil moisture data over large areas, reducing costs and enhancing agricultural productivity.
Overview
The pivot mounted cosmic-ray neutron sensor (CRNS) represents a significant advancement in irrigation scheduling technology. This innovative system leverages cosmic-ray physics to measure soil moisture over large areas, providing an integrated moisture estimate without the need for intrusive soil probes. By eliminating the requirement for seasonal removal of traditional probes, this solution addresses a major barrier to adoption, offering farmers a more efficient and less labor-intensive method of irrigation management.
Technical specifications
Key features:
- Utilizes cosmic-ray neutron sensors to measure soil moisture over several acres
- Pivot mounted design eliminates the need for probe removal between seasons
- Cost-effective with decreasing sensor costs, targeting $5k per unit
- Low power consumption and global data transfer capabilities through iridium data
- Simple installation and calibration, completed within 30 minutes
