  • Temperature compensated soil moisture sensor
    Patent number: 5430384
    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.
