Soil Moisture Hobo Smart Sensor 10HS (over a Large area of influence)

Measure 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 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.

Features:

• Measures a large 1-liter volume of soil, providing a more accurate picture of average soil moisture
• Provides data directly in volumetric water content
• Sensor uses a high-frequency (70 MHz) circuit that provides good accuracy even in high-salinity and sandy soils.
• Compatible with Onset standalone and web-based weather stations

Details

Measurement Range:
In soil: 0 to 0.570 m/m (volumetric water content)

Accuracy: 0.033 m/m (3%) typical 0 to +50C (+32 to +122F) for mineral soils up to 10 dS/m
0.020 m/m (2%) with soil specific calibration

Resolution: 0.0008 m/m (0.08%)

Soil Probe Dimensions: 160 x 32 x 2 mm (6.5 x 1.25 x 0.08 in.)

Weight: 190 grams (6.7 oz)

Decagon Probe Part No.: 10HS

Sensor Operating Temperature:
0 to +50C (+32 to +122F). Although the sensor probe and cable can safely operate at below-freezing temperatures (to -40C/F) and the smart sensor tube (the white portion of the sensor cable that houses the electronics) can be exposed to temperatures up to +70C (+158F), the soil moisture data collected at these extreme temperatures is outside of the sensor’s accurate measurement range. Extended temperatures above +50C (+122F) will decrease logger battery life when using for the S-SMD-M005 smart sensor.

Volume of Influence: 1 liter (33.8 oz)

Sensor Frequency: 70 MHz

Bits per Sample: 12

Number of Data Channels: 1

Measurement Averaging Option: No

Cable Length Available: 5 m (16 ft)

Length of Smart Sensor Network Cable: 0.5 m (1.6 ft)
