ABSTRACT:
A resistive soil moisture sensor which is implanted in the soil includes a temperature sensitive component, located at the same soil depth as the sensor. The thermistor is part of a thermistor network which includes other components which are located above ground. The resultant sensor automatically compensates for temperature variations, and is well suited for use with data loggers and automatic control systems.
