S-SMD-M005 10HS Soil Moisture Smart Sensor

Description

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

Specifications

• Measurement Range: In soil: 0 to 0.570 m³/m³ (volumetric water content)
• Accuracy:
  ±0.033 m³/m³ (±3.3%) typical 0 to +50°C (+32° to +122°F) for mineral soils up to 10 dS/m
  ±0.020 m³/m³ (±2%) with soil specific calibration
• Resolution: 0.0008 m³/m³ (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 +50°C (+32° to +122°F).
  Although the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F) and the smart sensor tube (the white portion of the sensor cable that houses the electronics) 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 for the S-SMD-M005 smart sensor.
