Measure soil water content with the affordably-priced 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 temperature effects and a wide measurement range.
