The HOBO S-SMD Soil Moisture Smart Sensor measures soil moisture over a large volume of soil. This sensor
integrates the field-proven 10HS Sensor and a 12-bit A/D, providing ±3% accuracy in most soils conditions,
and ±2% accuracy with soil-specific calibration. The 10cm probes measure soil moisture over a larger volume
of soil which helps to average out any soil variability. Readings are provided directly in volumetric water
content. This sensor’s high frequency design gives it a low sensitivity to salinity and textural effects and
a wide measurement range.
