2. TDR moisture sensor - Wikipedia

   en.wikipedia.org/wiki/TDR_moisture_sensor

   A TDR waveguide with exposed wires. In the waveform analysis a sensor (usually a probe) is placed in the material to be tested. The sensor contains a waveguide consisting of two, three, or more parallel wires which is connected via a coaxial cable to a voltage pulse generator which sends precisely defined voltage pulses into the sensor.

3. Time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Time-domain_reflectometer

   The sensors can output the analyzed level as a continuous analog signal or switch output signals. In TDR technology, the impulse velocity is primarily affected by the permittivity of the medium through which the pulse propagates, which can vary greatly by the moisture content and temperature of the medium.

4. Soil moisture sensor - Wikipedia

   en.wikipedia.org/wiki/Soil_moisture_sensor

   A simple soil moisture sensor for gardeners. Soil moisture sensors measure the volumetric water content in soil. [1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant ...

5. Frequency domain sensor - Wikipedia

   en.wikipedia.org/wiki/Frequency_domain_sensor

   Compared to time domain reflectometer (TDR), FD sensors are cheaper to build and have a faster response time. However, because of the complex electrical field around the probe, the sensor needs to be calibrated for different soil types. Some commercial sensors have been able to remove the soil type sensitivity by using a high frequency.
