Abstract

Embodiments of the disclosed technology are directed to methods, systems, and/or apparatuses for monitoring and maintaining hydration levels in plants. The technology employs a base onto which a plant is placed. The base may have a built-in scale, as well as a spout for dispensing water. The spout may be coupled to a water supply via a pump. The scale may be coupled to a processor used to weigh the plant, detect fluctuations in weight, and/or to initiate/cease dispensing of water to the plant based on detected parameters. A leak sensor may also be incorporated into the spout for cutting off the water supply upon detection of possible over-watering. The base may also have an input for facilitating user control over the irrigation frequency and dosage.

Claims

1. A system for watering a plant, comprising:

a base adapted for receiving said plant, said base having a scale engaged with a surface thereof;

a spout coupled to a water supply for directing water into said plant;

a control for manually controlling said water; and

a liquid capacitance sensor disposed on said surface of said base;

wherein, upon said liquid capacitance sensor detecting liquid, said spout stops dispensing liquid from said water supply.

2. The system of claim 1, wherein said liquid capacitance sensor comprises:

a vessel adapted to collect water; and

an electric circuit having two capacitance plates disposed on an interior surface of said vessel, such that the presence of water in said vessel submerges said capacitance plates, thereby activating said circuit.

3. The system of claim 1, wherein said scale is operable to continuously measure a weight of said plant and to cause water to be directed into said plant upon a detected reduction in weight of said plant.

4. The system of claim 1, wherein said scale is configured to trigger watering through said spout upon a weight of said plant dropping below a predefined threshold.

5. A method of watering a plant comprising:

receiving a sufficiently watered plant on a base, said base having an electronic scale incorporated therein;

measuring and storing an initial weight of said sufficiently watered plant;

detecting a reduction of weight of said plant;

dispensing water onto said plant; and

ceasing said dispensing of water upon detecting that said plant has reached at least said initial weight.

6. The method of claim 5, further comprising:

detecting an overflow of water during said dispensing, and ceasing said dispensing in response thereto.

7. The method of claim 6, wherein said overflow is detected by a liquid capacitance sensor.

8. The method of claim 5, wherein said detectable reduction in weight exceeds a measurable threshold.

9. The method of claim 8, wherein threshold is pre-defined via an input associated with said base.

10. A method of watering a plant comprising:

receiving a plant on a base, said base having a spout and scale;

measuring an initial weight of said plant;

directing an amount of water into said plant, said amount of water being equal in weight to 25% of said initial weight of said plant;

re-measuring a new weight of said plant and comparing said new weight to 125% of said initial weight; and

dosing water to said plant until said new weight is greater than, or equal to, 125% of said initial weight.

11. The method of claim 10, further comprising:

detecting if said plant has been over-watered, using a leak sensor.

12. The method of claim 10, wherein said step of dosing water is carried out in increments of 5% of said initial weight.

13. The method of claim 10, wherein said step of dosing water is carried out in increments of 1% of said initial weight.
