- Soil moisture sensors
Soil moisture sensors measure the
water contentin soil. A soil moisture probe is made up of multiple soil moisture sensors. One common type of soil moisture sensors in commercial use include the Frequency domain sensorsuch as the capacitance sensor. One of the major manufacturers of soil moisture sensors and probes is [http://www.aquaspy.com AquaSpy] .
Measuring soil moisture is important in agriculture to help farmers manage their irrigation systems more efficiently. Not only are farmers able to generally use less water to grow a crop, they are able to increase yields and the quality of the crop by better management of soil moisture during critical plant growth stages.
Besides agriculture, there are many other disciplines using soil moisture sensors. Golf courses are now using sensors to increase the efficiencies of their irrigation systems to prevent over watering and leaching of fertilizers and other chemicals offsite.
In urban areas, landscapes and residential lawns are using soil moisture sensors to interface with an irrigation controller. Connecting a soil moisture sensor to a simple irrigation clock will convert it into a “smart” irrigation controller that prevents an irrigation cycle when the soil is wet. An example of a controlling soil moisture sensor is the [http://www.aquaspy.com/default.cfm?id=201 AquaBlu] .
