2. 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 ...

   en.wikipedia.org/wiki/Tensiometer_(soil_science)

   When the soil is wetted flow can also occur in the reverse direction: as water is added to the soil, the vacuum inside the tube pulls moisture from the soil and decreases. When the water pressure in the tensiometer is determined to be in equilibrium with the water pressure in the soil, the tensiometer gauge reading represents the matric ...

5. Moisture meter - Wikipedia

   en.wikipedia.org/wiki/Moisture_meter

   Moisture meters are measuring instruments used to measure the percentage of water in a given substance, as physical properties are strongly affected by moisture content and high moisture content for a period of time may progressively degrade a material. Meters exist for various substances, including wood, building materials, concrete, and soil.

6. 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.
