  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 ...

  3. 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.

  4. Moisture meter - Wikipedia

    en.wikipedia.org/wiki/Moisture_meter

    Measuring water leakage in exterior wall with Trotec T660 Moisture Measuring Device, using dielectric measurement method (indicative). 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.

  5. Frequency domain sensor - Wikipedia

    en.wikipedia.org/wiki/Frequency_domain_sensor

    Frequency domain (FD) sensor is an instrument developed for measuring soil moisture content. The instrument has an oscillating circuit, the sensing part of the sensor is embedded in the soil, and the operating frequency will depend on the value of soil's dielectric constant.

  6. Hygrometer - Wikipedia

    en.wikipedia.org/wiki/Hygrometer

    A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.

  7. Moisture analysis - Wikipedia

    en.wikipedia.org/wiki/Moisture_analysis

    The oxide sensor is made up of an inert substrate material and two dielectric layers, one of which is sensitive to humidity. The moisture molecules pass through the pores on the surface and cause a change to the physical property of the layer beneath it. An aluminum oxide sensor has two metal layers that form the electrodes of a capacitor.
