<p><strong>INTRODUCTION & OBJECTIVES:</strong></p>
<p>I is a simple system, using <a href="http://bit.ly/26nCm2w" itemprop="url" target="_bank" title="Arduino"><strong>Arduino</strong></a> to automate the irrigation and <a href="http://bit.ly/1PhV7d2" itemprop="url" target="_bank" title="watering"><strong>watering</strong></a> of small potted plants or crops.<br />
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 <a href="http://bit.ly/1Ug9zrI" itemprop="url" target="_bank" title="Arduino Automatic Watering System"><strong>watering</strong></a> plants.<br />
The system uses a LCD display to notify all actions that are taking place and a real time clock.</p>
<p>The Theory (from Wikipedia):<br />
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.<br />
Volumetric water content, θ, is defined mathematically as:</p>

<p>where  is the volume of water and  is the total volume (that is soil volume + water volume + air space).<br />
Gravimetric water content<a class="ext-link" href="http://bit.ly/1Ug9K69" rel="nofollow external nofollow" target="_blank">[1]</a> is expressed by mass (weight) as follows:</p>
<p>where  is the mass of water and  is the bulk mass. The bulk mass is taken as the total mass, except for <a class="ext-link" href="http://bit.ly/1PhV4Ot" rel="nofollow external nofollow" target="_blank" title="Geotechnical">geotechnical</a> and soil science applications where oven-dried soil (, see the diagram) is conventionally used as .<br />
To convert gravimetric water content to volumetric water, multiply the gravimetric water content by the bulk <a class="ext-link" href="http://bit.ly/1Ug8Re4" rel="nofollow external nofollow" target="_blank" title="Specific gravity">specific gravity</a> of the material.<br />
In <a class="ext-link" href="http://bit.ly/1PhUDnl" rel="nofollow external nofollow" target="_blank" title="Soil mechanics">soil mechanics</a> and <a class="ext-link" href="http://bit.ly/1Ug9aFx" rel="nofollow external nofollow" target="_blank" title="Petroleum engineering">petroleum engineering</a>, the term water saturation or degree of saturation,  is used, defined as</p>
<p>where  is the <a class="ext-link" href="http://bit.ly/1PhUzDV" rel="nofollow external nofollow" target="_blank" title="Porosity">porosity</a> and  is the volume of void or pore space. Values of <em>Sw</em> can range from 0 (dry) to 1 (saturated). In reality, <em>Sw</em> never reaches 0 or 1 – these are idealizations for engineering use.<br />
The normalized water content, , (also called effective saturation or ) is a dimensionless value defined by van Genuchten<a class="ext-link" href="http://bit.ly/1Ug9RPc" rel="nofollow external nofollow" target="_blank">[2]</a> as:</p>
<p>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, .</p>

<p>In the Pictures you have an overview of the components used.</p>
<p>Data from the soil moisture sensor set:<br />
When the soil is dry, the impedance will be high and the LM-393 will show a high value on the output.<br />
When the soil is wet, it will show a low value in the output.<br />
The 3 LEDs range can be defined as:<br />
– Soggy soil –  moisture between 0 and 500;<br />
– Wet soil – moisture between 500 and 800;<br />
– Dry soil – moisture between 800-1023;<br />
The module has one digital output and an analog output. (in the project, should be used to analog output)</p>
<p>The water level sensor:<br />
This sensor must be made (homemade) on phenolite board, with spacings of 1 mm between trails and trails with 1 mm of thickness.</p>
