2. Rain Clox - Wikipedia

   en.wikipedia.org/wiki/Rain_Clox

   1970 advertisement for RC-12 and moisture sensor. Rain Clox was the trade name given to a series of electromechanical irrigation controllers produced by the Rain Bird Corporation from 1962 to the late 2000s (decade), and were largely responsible for giving rise to the widespread use of automatic irrigation. The first model was the ME11AB ...

3. 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 ...

4. Irrigation controller - Wikipedia

   en.wikipedia.org/wiki/Irrigation_controller

   Some controllers have additional features such as multiple programs to allow different watering frequencies for different types of plants, rain delay settings, input terminals for sensors such as rain and freeze sensors, soil moisture sensors, weather data, remote operation, etc. There are two basic types of controllers, electric and hydraulic.

5. Tensiometer (soil science) - Wikipedia

   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 ...

6. Frequency domain sensor - Wikipedia

   en.wikipedia.org/wiki/Frequency_domain_sensor

   Capacitance probe, or fringe capacitance sensor.Capacitance probes use capacitance to measure the dielectric permittivity of the soil. The volume of water in the total volume of soil most heavily influences the dielectric permittivity of the soil because the dielectric constant of water (80) is much greater than the other constituents of the soil (mineral soil: 4, organic matter: 4, air: 1).

7. Moisture meter - Wikipedia

   en.wikipedia.org/wiki/Moisture_meter

   A moisture meter gives a reading of the approximate moisture content of wood. The reading helps in determining whether the wood is suitably dry for its intended purpose. The moisture content reading can also assist in planning a project design that will accommodate future changes in dimension caused by changes in relative humidity.

9. TDR moisture sensor - Wikipedia

   en.wikipedia.org/wiki/TDR_moisture_sensor

   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. As the pulse travels along the waveguide its progress varies depending on the moisture content of the material being examined.
