We have soil sensors buried in the ground at the levels indicated below.
Each level has a temperature probe and a moisture sensor.

Water potential is commonly measured in units of bars (and centibars in the English system of measurement) or kilopascals (in metric units).
One bar is approximately equal to one atmosphere (14.7 lb/in 2 ) of pressure. One centibar is equal to one kilopascal.
Buttton text | Explanation |
Saturated
(0 - 11 cb) |
Saturated Soil. Occurs for a day or two after irrigation. |
Adequate
(11 - 26 cb) |
Soil is adequately wet (except coarse sands which are drying out at this range) |
Irrigation desired
(26 - 61 cb) |
Usual range to irrigate or water (except heavy clay soils). Irrigate at the upper end of this range in cool humid climates and with higher water-holding capacity soils. |
Irrigation needed
(61 - 101 cb) |
Usual range to irrigate heavy clay soils |
Dangerously Dry
(101 - 240 cb) |
Soil is becoming dangerously dry for maximum production. |
