Hobo S-SMD-M005 – LI-COR

This sensor measures the soil moisture over a large volume of soil with the affordably-priced 10HS Soil Moisture Smart Sensor. 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 10 cm 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.

This is a plug-and-play smart sensor, who is compatible with RX, H21, H22, and U30 loggers (stations). Also available in a wireless model for use with the HOBOnet Field Monitoring System. This sensor measures a large 1-liter volume of soil, providing a more accurate picture of average soil moisture and provides the data directly in volumetric water content. The high-frequency (70 MHz) circuit provides good accuracy even in high-salinity and sandy soils. This sensor operates in an outdoor environment and the S-SMD-M005 sensor supports the following measurement: soil moisture.
