Device, system, and method of irrigation
First Claim
1. An irrigation system for irrigating a plant having a root, the irrigation system comprising:
- a valve to begin irrigation from a water source at a first time-point;
a single moisture sensor to sense moisture at a second, subsequent, time-point, said moisture sensor being located underground at an insertion depth between ground surface and a maximum depth;
a water drainage speed calculator to calculate a water drainage speed based on the first time-point, the second time-point, and the insertion depth of the moisture sensor; and
a target drainage time calculator to calculate a remaining time for irrigation, based on the calculated water drainage speed and further based on a difference between the insertion depth and the maximum depth.

Abstract
An irrigation system for irrigating a plant having a root comprises: a valve to begin irrigation from a water source at a first time-point; a moisture sensor to sense moisture at a second, subsequent, time-point, said moisture sensor being located underground at an insertion depth between ground surface and a maximum depth of the root; a water drainage speed calculator to calculate a water drainage speed based on the first time-point, the second time-point, and the insertion depth of the moisture sensor; and a target drainage time calculator to calculate a remaining time for irrigation, based on the calculated water drainage speed and further based on a difference between the insertion depth and the maximum depth of the root.

9. A method for irrigating a plant having a root, the method comprising:
-
beginning irrigation from a water source at a first time-point; sensing moisture at a second, subsequent, time-point, by a single moisture sensor being located underground at an insertion depth between ground surface and a maximum depth of the root; calculating a water drainage speed based on the first time-point, the second time-point, and the insertion depth of the moisture sensor; and calculating a remaining time for irrigation, based on the calculated water drainage speed and further based on a difference between the insertion depth and the maximum depth of the root. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
