Abstract
A method for measuring moisture content and salt concentration contained in soil is provided. It is based on an idea of using a ratio of microwave signals propagating through a microstripline. Using the microwaves at 2 GHz and 10 GHz, the measurement is carried out on a sample of sand. Although the measurement result has non-negligible error, it confirms that the sensor has an ability of measuring the moisture content and salt concentration.
Claims15
A sensor system for measuring moisture content and salt concentration in soil comprising:
- a microstripline board having a microstripline over which a sample is put;
- an analyzer, connected to the microstripline board, for applying microwave to an input side of the microstripline to provide measured data of the sample from an output side of the microstripline;
- and
- a processor, connected to the analyzer, for storing and processing measured data.
