HOBO Soil Moisture Smart Sensor
Onset Sensor to Monitor Soil Conditions and Volumetric Soil Content
 The HOBO Soil Moisture Smart Sensor measures soil water content. This sensor integrates the field-proven ECH2O™ Sensor and a 12-bit A/D, providing ±4% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration. The sensor, with its thin profile, probe length (available in 5,10 and 20-cm) easy installation, provides a representative cross-section of soil measurement. Readings are provided directly in volumetric water content.
