Development of a Current Injection—Type Impedance Measurement System for Monitoring Soil Water Content and Ion Concentration

Development of a Current Injection—Type Impedance Measurement System for Monitoring Soil Water Content and Ion Concentration

This study was conducted with the aim of developing a circuit system that enables the measurement of the moisture content and ion concentration with a simple circuit configuration. Our previous studies have shown that soil can be represented by an equivalent circuit of a parallel circuit of resistor...
