SOIL MOISTURE SENSOR USING ARDUINO WITH CONNECTION AND CODE

SOIL MOISTURE SENSOR USING ARDUINO WITH CONNECTION AND CODE

Soil moisture sensor is the sensing element which determine the volumetric amount of water in the soil .The sensor sense the amount of water by passing an minute voltage at its terminal .Then when the water presence is detected it send an minute voltage to the amplifying circuit and it is further amplified and send to the Arduino.

Components Required:

                      1) Arduino

                      2) Soil Moisture sensor

                      3) Led

                      4) Connecting wires

Procedure:

                  STEP 1: Take the arduino and connect it to soil moisture sensor.

                  STEP 2: Connect the +vcc pin of soil moisture sensor to the +5v pin of the arduino and connect GND pin of sensor to the GND of the arduino

                  STEP 3: Connect the A0 pin of the soil moisture sensor to the arduino

                  STEP 4: Connect led  positive to the 13pin of the arduino and connect GND to GND pin of the arduino.

                STEP 5: Now copy the code given below and compile it to the arduino and run it.

                

                  

Source Code:

int led = 13;//NBSL COMMERCIAL

void setup() {

  Serial.begin(9600);

Serial.println("NBSL COMMERCIAL");

    pinMode(led, OUTPUT);

}

void loop() {

  int sensorValue = analogRead(A0);

  Serial.println("SOIL" );

  Serial.println(sensorValue);

  delay(1);

  if (sensorValue >A 1000)

 {

  Serial.println("WATER PRESENCE FOUND");

  digitalWrite(led, HIGH);

   delay(1000);

 }

 else if (sensorValue < 1000)

 {

  Serial.println("NO WATER PRESENCE");

  digitalWrite(led, LOW);

   delay(1000);

 }

}
