Arduino Smart Garden Advanced

<p>Before you begin, please clear yourself a workspace, gather your Arduino Workbench, Arduino Smart Garden Add-On, and garden&nbsp;supplies from your teacher,&nbsp;and get your computer. A notebook and writing utensil are recommended, but not required.</p>

<p>Welcome to the Arduino Smart Garden: Advanced Course! You will be building off the knowledge you gained in the Arduino Smart Garden Basic Course to:</p>

<ul>
<li>Make a more advanced plant watering and monitoring system</li>
<li>Wire&nbsp;and code&nbsp;a temperature and humidity sensor</li>
<li>Use&nbsp;a temperature and humidity&nbsp;sensor to control a fan</li>
<li>Incorporate the temperature and humidity sensor into the soil moisture and pump/relay system to the circuit built in the Arduino Smart Garden Basics course</li>
<li>Design and assemble&nbsp;a greenhouse to grow&nbsp;pinto beans</li>
<li>Add&nbsp;temperature, humidity, and soil moisture sensors into the greenhouse to control the fan and pump outputs</li>
</ul>

<p>We will refer back to <a href="https://www.thespruce.com/pinto-beans-growing-guide-7508566">this guide for growing pinto beans</a>&nbsp;on what growing conditions&nbsp;the pinto bean needs.&nbsp;</p>

<p>Why do we care about temperature and humidity? We already set up an Arduino that can water a plant. Isn&#39;t that good enough?&nbsp;</p>

<p>Well, not quite. Your beans could likely grow okay in your classroom. But, a greenhouse is a way to insulate your plant from swings in temperature. And, you want to monitor/regulate temperature and humidity. Too hot and your plants die. Too humid and your plants are at risk for fungal infections.</p>

<p>The key is to keep your plants in the zone where they are most happy and your Arduino is the right tool to optimize the growing environment for your pinto beans!</p>

<p>Sensors are important to your Arduino smart garden. Without sensors, your Arduino is &quot;blind&quot; and cannot sense what is happening with your plant. In this step, you will learn about how the DHT11 sensor measures temperature and then you will use the Arduino Workbench to hook up the DHT11 sensor.</p>

<p><img alt="David Watson, https://www.theengineeringprojects.com/2019/02/introduction-to-dht22.html, 2019" src="https://images.theengineeringprojects.com/image/webp/2019/02/intro-to-dht22.jpg.webp?ssl=1" style="height: 369px; width: 600px;" /></p>

<p>Temperature is monitored with the DHT11&nbsp;Temperature/Humidity module. Under the plastic (either blue or white) cover, there is a thermistor. A thermistor is a temperature variable resistor (thus &quot;therm-istor&quot;). So when the temperature of the thermistor changes, the resistance changes, and that information is converted into temperature changes.</p>

<p>Below here, is a wiring guide and a video wiring guide for your DHT11 sensor!</p>
