Davis Soil Moisture Sensor

The Davis Soil Moisture Sensor is a professional-grade instrument designed for agricultural professionals, landscapers, and serious gardeners who need precise soil hydration monitoring. This sensor integrates seamlessly with Davis Vantage Pro® and Vantage Pro2™ weather stations, enabling real-time soil moisture data collection directly from your growing areas. Whether managing irrigation schedules for crops, turf, or ornamental plantings, this sensor eliminates guesswork and helps optimize water use efficiency across residential and commercial applications.

The Davis Soil Moisture Sensor employs Watermark® electrical resistance technology to accurately measure soil water potential at the installation depth. Simply bury the sensor at the target depth—typically 6, 12, or 24 inches depending on your crop's root zone—and the integrated resistance elements detect moisture changes without requiring calibration or periodic maintenance during the growing season. The compact, durable design (4 x 1 x 6 inches, weighing just 0.3 lbs) ensures minimal soil disruption and long-term reliability in field conditions. This passive measurement approach requires no external power at the sensor itself, reducing installation complexity.

Ideal for drip irrigation automation, precision agriculture operations, and landscape maintenance programs, the Davis Soil Moisture Sensor delivers actionable moisture data that directly informs irrigation timing and volume decisions. Compatible exclusively with Davis Vantage Pro® and Vantage Pro2™ weather console systems, it integrates into existing Davis monitoring networks for unified environmental data collection. Installation is straightforward: bury the sensor horizontally or at a slight angle at your chosen depth, ensuring good soil contact, then connect the sensor cable to your weather station console. Monitoring soil moisture at multiple depths provides a comprehensive understanding of water availability throughout the root zone, enabling water conservation and improved crop performance.
