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, helping to average out any soil variability. Readings are provided directly in volumetric water content. The sensor's high-frequency design minimizes salinity and textural effects and gives it a wide measurement range.
Also available in a wireless model for use with the HOBOnet Field Monitoring System.

Note
Although the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F) and the smart sensor tube can be exposed to temperatures up to +70°C (+158°F), the soil moisture data collected at these extreme temperatures is outside of the sensor's accurate measurement range. Extended temperatures above +50°C (+122°F) will decrease logger battery life when using the S-SMD-M005 smart sensor.
