+
+ <p>The DHT11 sensor has 4 pins, but is often sold on a carrier board which has 3 pins. It communicates with the Arduino very simply through one of its digital inputs. The other 2 pins are for its 5V supply and ground (GND).</p>

+ <h4>Soil Moisture Sensor (infos from <a href="https://maker.pro/arduino/projects/arduino-soil-moisture-sensor" target="_blank">Maker Pro</a>)</h4>
+
+ <p>The soil moisture sensor consists of two probes that are used to measure the volumetric content of water. The two probes allow the current to pass through the soil, which gives the resistance value to measure the moisture value.</p>

+
+ <p>When there is water, the soil will conduct more electricity, which means that there will be less resistance. Dry soil conducts electricity poorly, so when there is less water, then the soil will conduct less electricity, which means that there will be more resistance.</p>
+
+ <p>This sensor can be connected in analog and digital modes. First, we will connect it in analog mode, and then digital.</p>
+
+ <h5>Specifications</h5>
+ <p>The specifications of the FC-28 soil moisture sensor are as follows:</p>
+ <ul>
+ <li>Input Voltage: 3.3–5V</li>
+ <li>Output Voltage: 0–4.2V</li>
+ <li>Input Current: 35mA</li>
+ <li>Output Signal: both analog and digital</li>
+ </ul>
+
+ <h5>Pin-out</h5>
+ <p>The FC-28 soil moisture sensor has four pins:</p>
+ <ul>
+ <li>VCC: Power</li>
+ <li>A0: Analog Output</li>
+ <li>D0: Digital Output</li>
+ <li>GND: Ground</li>
+ </ul>
+
+ <span class="image object">
+ <img src="../images/sensor-moisture-pinout.WebP" alt="...">
+ </span>
+
+ <p>The module also contains a potentiometer, which will set the threshold value. This threshold value will be compared by the LM393 comparator. The output LED will light up and down according to this threshold value.</p>
