Soil Moisture and Temperature
The soil sensors are buried in the ground at the levels indicated below. Each level has a temperature probe and a moisture sensor.
Moisture is measured in Centibars (cb) with a range of 0 to 200 with 0 being totally saturated and anything over 100 being extremely dry. The centibar (cb) is an agricultural unit of soil water tension (water pressure on plant roots).
For planning purposes, if your home is located close to the Tyler Texas Weather site or in other areas of Tyler with similar loamy sand soil, you can use the "Estimated Days Until Watering is Required" value displayed in the sidebar. You can view the various soil types throughout Smith County, Texas along with the location of Tyler Texas Weather here.
