This affordably-priced soil moisture smart sensor offers a two-tine design for easy installation. This sensor integrates the field-proven ECH2O EC-5 Sensor and a 12-bit A/D. It provides ±3% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration. Readings are provided directly in volumetric water content. This sensor is designed to maintain low sensitivity to salinity and textural effects.
This is a plug-and-play smart sensor, who is compatible with RX, H21, H22, and U30 loggers (stations). Also available in a wireless model for use with the HOBOnet Field Monitoring System. The sensor measures a 0,3-liter volume of soil and is compatible for smaller measurement volume for use in containers or measuring at multiple depths. The high-frequency (70 MHz) circuit provides good accuracy even in high-salinity and sandy soils.
This sensor operates in an outdoor environment and the S-SMC-M005 sensor supports the following measurement: soil moisture.
