Measure soil water content with the affordably-priced EC-5 Soil Moisture Smart Sensor; this sensor integrates the field-proven ECH2O™ Sensor and a 12-bit A/D, providing ±3% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration. The sensor’s two-tine design makes the sensor easy to install. Readings are provided directly in volumetric water content. This sensor's high frequency design gives it a relatively low sensitivity to salinity and textural effects and a wide measurement range.
Environment:The S-SMC-M005 Sensor is for use in Outdoor environments
Measurements:The S-SMC-M005 Sensor supports the following measurements :
Measurement RangeIn soil: 0 to 0.550(m³/m³)Extended range: -0.401 to 2.574 m³/m³ (full scale)The sensor is capable of providing readings outside the standard volumetric water content range. This is helpful in diagnosing sensor operation and installation. See the Operation section below for more details.Accuracy: ±0.031 m³/m³ (±3%) typical 0 to 50°C (32° to 122°F); ±0.020 m³/m³ (±2%) with soil specific calibration.This is a system level accuracy specification and is comprised of the ECH2O probe's accuracy of ±0.03 m³/m³ typical (±0.02 m³/m³ soil specific) plus the smart sensor adapter accuracy of ±0.001 m³/m³ at 25°C (77°F). There are additional temperature accuracy deviations of ±0.003 m³/m³ / °C maximum for the ECH2O probe across operating temperature environment, typical <0.001 m³/m³ / °C. (The temperature dependence of the smart sensor adapter is negligible.)Resolution: ±0.0007 m³/m³ (±0.07%)Soil Probe Dimensions: 89 x 15 x 1.5 mm (3.5 x 0.62 x 0.06 in.)Weight: 180 grams (6.3 oz)Decagon ECH2O Probe Part No.: EC-5Sensor Operating Temperature: 0° to 50°C (32° to 122°F). While the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F) and up to 75°C (167°F), the soil moisture data collected at these extreme temperatures is outside of the sensor's accurate measurement range.
