Smart soil moisture sensor EC5 S-SMC-M005

One smart soil moisture sensor affordable with a design with two teeth for one easy installation.
This is sensor integrates eCH 2 O EC-5 sensor tested in the field and A/D 12 bits, and provides an accuracy of ± 3 % in typical soil conditions and precision of ± 2 % with one ground specific calibration.
Readings are provided directly in volumetric moisture content.
This sensor is designed to maintain a low sensitivity to the salinity and texture effects.
Also available in a wireless model for use with the field monitoring system HOBOnet.

Technical specifications:

- Measure a soil volume of 0.3 litres
- Smaller measurement volume for use in containers or for measurement at several depths
- The high frequency circuit (70 MHz) offers good precision even in saline and sandy soils
- Compatible with autonomous and Web weather stations Onset

Sensor Features:

- Measurement range:
In soil: 0 to 0.550(m3/m3)
Wide 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 useful for diagnosing the operation and installation of the sensor. See the user manual for more information.
- Accuracy:
±0.031 m3/m3 (±3.1%) typical 0 at 50°C (32° to 122°F)
±0.020 m3/m3 (±2%) with specific ground calibration
This is a system-specific precision specification and includes the accuracy of the typical ±0.03 m3/m3 ECH2O probe (±0.02 m3/m3 soil-specific) plus the accuracy of the smart sensor adapter from ±0.001 m3/m3 to 25 °C (77 °F).
There are additional temperature accuracy deviations of ±0.003 m3/m3 / °C maximum for the ECH2O probe in the typical operating temperature environment (The temperature dependence of the smart sensor adapter is negligible. )
- Resolution: 0.0007 m3/m3 (0.07%)
- Dimensions of the soil probe: 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 reference: EC-5
- Sensor operating temperature: 0° to 50°C (32° to 122°F).
Although the sensor probe and cable can operate safely at temperatures below freezing point (up to -40°C/F) and up to 75°C (167°F), soil moisture data collected at these extreme temperatures are outside the accuracy of the measuring range sensor.
- Volume of influence: 0.3 litres (10.1 oz)
- Sensor frequency: 70 MHz
- Bits per sample: 12
- Number of data channels: 1
- Option for calculating the average of measurements: No
- Cable length available: 5 m (16 ft)
- Smart Sensor network cable length: 0.5 m (1.6 ft)

Note: A single HOBO recorder compatible with smart sensors can support 15 data channels and up to 100 m (328 ft) smart sensor cable (the digital communication part of sensor cables)
