WATERING SYSTEM - INTRODUCTION

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.

Awesome!
Great Job.

Seems to be a professional system.

Congratulations.
Hi Marcelo
Thanks and thanks to you for the project.

Hello! I was inspired with your Arduino Watering System. I'd like to try to build the same plant system, could you email the code and libraries? My email is ma3gel.29@gmail.com

Thanks a lot!

Hi you all ! Would anyone out there know how to rewrite this code to work with the DS1302 module ? Im lacking the experience and would need it for my greenhouse soon.

Regards

Theo

BIGDOG1971 (author)  theohegg24 days ago
I have no experience with DS1302, so sorry.

I sent after a ds1307 but due to HD crash I've lost the codes. Would you send them and the libraries to me ?

dhaggaland@gmail.com

Theo

does anyone know how to initialize and assign more sensors and pumps? im taking out the led's and buzzer to make room on the uno, but the pin definition numbers overlap (both digital 3 and analog 3 are being used)...any idea how to modify for multiple plant sensors and pumps?

Been considering something like this one for a while. I would like to add a few more plants, each with a sensor and flow., Please send your code & libs. Any thoughts on adding the additional plants? Certainly, solenoids to control the water distribution.

Stew

Hi Stewl.

Send me an email and I will share de code and libraries with you.

Olá amigo, legal demais o projeto. Estou tentando construir um sistema desses pois viajo muito e minha plantas acabam morrendo. Seria possível me enviar o código e as livrarias do projeto para que eu possa tentar montar também?

Grande abraço!

I like your tutorial! Very helpful!

Here's a great source for cheap sensors and other parts that you need for this project:

http://voltatek.com/en/

They sell humidity/water sensors, soil humidity sensor, real time clock, etc...
