Soil Moisture Sensor Project

  Components Required :

• Arduino set
• Soil moisture sensor
• LEDs
• Relay (6V)

Arduino

Soil Moisture sensor

LEDs

Relay (6V)

Circuit Diagram : 

Connections :

  

• Connect Vcc Pin of Soil Moisture sensor to 5v Pin of Arduino.
• Connect GND pin of Soil Moisture sensor to GND pin of Arduino
• Connect Data pin of Soil Moisture sensor to Analog Pin of Arduino (i.e.  Pin 0)

Arduino Program :

/* # the sensor value description

# 0  ~300     dry soil

# 300~700     humid soil

# 700~950     in water*/

void setup(){

Serial.begin(9600);

}

void loop(){

int soil_moisture=analogRead(A0);  // read from analog pin A3

Serial.print(“analog value: “);

if(soil_moisture<30) {

Serial.println(“Dry soil”);

}

if((soil_moisture>300)&&(soil_moisture<700)) {

Serial.println(“Humid soil”);

}

if((soil_moisture>700)&&(soil_moisture<950)){

Serial.println(“water”);

}

}
