Instructables
Picture of WATERING SYSTEM - INTRODUCTION
INTRODUCTION & OBJECTIVES:
 
I is a simple system, using Arduino to automate the irrigation and watering of small potted plants or crops.
This system does the control of soil moisture, doing indications via LEDs and in case of dry soil emitting a alarm beep. In case of dry soil it will activate the irrigation system pumping water for watering plants.
The system uses a LCD display to notify all actions that are taking place and a real time clock.
 
 
The Theory (from Wikipedia):
Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, fruit, or wood. Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation. It can be given on a volumetric or mass (gravimetric) basis.
Volumetric water content, θ, is defined mathematically as:

where  is the volume of water and  is the total volume (that is soil volume + water volume + air space).
Gravimetric water content[1] is expressed by mass (weight) as follows:

where  is the mass of water and  is the bulk mass. The bulk mass is taken as the total mass, except for geotechnical and soil science applications where oven-dried soil (, see the diagram) is conventionally used as .
To convert gravimetric water content to volumetric water, multiply the gravimetric water content by the bulk specific gravity of the material.
In soil mechanics and petroleum engineering, the term water saturation or degree of saturation,  is used, defined as

where  is the porosity and  is the volume of void or pore space. Values of Sw can range from 0 (dry) to 1 (saturated). In reality, Sw never reaches 0 or 1 - these are idealizations for engineering use.
The normalized water content, , (also called effective saturation or ) is a dimensionless value defined by van Genuchten[2] as:

where  is the volumetric water content;  is the residual water content, defined as the water content for which the gradient  becomes zero; and,  is the saturated water content, which is equivalent to porosity, .

My first Arduino project, after much messing about I got it right, even added more code to operate a water valve to open when the water tank becomes low.

​Hi, sry for disturbing you. Can u gve me simulation circuit for watering system project if u have it. And what software do you prefer to make simulation. Ty!

Awesome!
Great Job.

Seems to be a professional system.

Congratulations.

You should think about making an instructable of your own! That looks awesome!

Hi man,
did you use a relay or nn?

Hi,

Yes I used a relay to start the pump. The Arduino is not capable of delivering the current the motor needs.

I can not compile the sketch, this is the error message:

"This report would have more information with

"Show verbose output during compilation"

enabled in File > Preferences.

Do you know what can be bothering here??? Thanks!

Hi,

This kind of issue is due to libraries installation failure.
To solve the problem, proceed as shown below.

Remove all project libraries from the "libraries" folder.
To install the library(ies), follow the steps below:
1 - take sure that the Arduino's IDE is closed;
2 - unzip the library(ies) in the "libraries" folder of the Arduino's IDE;
3 - open the .ino file and compile it..

90% of people with this kind of problem, have solved it by following the procedure above.
If not, please re-install the arduino's IDE.


I hope I have helped you.

Feel free to send me your questions.


Best Regards

Hi, great diagrams, the download looks kind of sketchy...can you send the code, libraries and any other instructions please to: elfbong420@gmail.com

I am interested in having the data displayed on a web page with streaming camera also, to have the microcontroller-arduino run through raspberry pi.
