			Wire up water pipes with water pumps

			<br>[[File:图片1===2.png\|500px\|frameless\|thumb]]<br>

			F-F Dupont wires are connected to the positive pole of the water pump which is the red wire. Then they will be connected with the 5V pins on the motherboard.

			Test Result：

			Insert four soil moisture sensors into four plant pots, and put four water pump pipes in the pots. You can see that the LCD1602 display show soil moisture value. If soil is humid enough, the backlight of the LCD1602 display will be turned off after 10 seconds, which can save power. If soil lacks water, the backlight will light up, and water pumps will pump water to pots. After 3 seconds, the relay will be turned off, the water pump will stop pumping, and wait for 5 seconds, then the soil humidity sensor will continue to detect.

			}

			</pre>

			Test Result：

			S1 represents the soil sensor 1. Therefore, we can view the LCD1602 display show soil humidity values of four sensors，touch a sensor and observe the 1602 display

	=== Soil Humidity Sensor ===		=== Soil Humidity Sensor ===

			The soil humidity sensor is used for detecting soil humidity value, which can determine if your plants are desperate for water.

			'''Read values detected by soil sensors'''

			Description

			Read values of the 4 soil humidity sensors and print them out in serial monitor of Arduino IDE.


			'''Test Code'''

			<pre>
			#define soilPin1 A0
			#define soilPin2 A1
			#define soilPin3 A2
			#define soilPin4 A3

			void setup() {
			Serial.begin(9600);
			pinMode(soilPin1, INPUT);
			pinMode(soilPin2, INPUT);
			pinMode(soilPin3, INPUT);
			pinMode(soilPin4, INPUT);
			}

			int val1 = analogRead(soilPin1);
			int val2 = analogRead(soilPin2);
			int val3 = analogRead(soilPin3);

			Test Result

			Upload the test code and open the serial monitor of Arduino IDE, you can see that the values detected by the four soil humidity sensors are printed out. Touch the detection area of the sensor when your hands are wet, values on the monitor become smaller, which means that the more humid the soil, the smaller the measured value.<br>
