ARDUINO WITH MOISTURE SENSOR

In this tutorial you will get to know that how you can create an moisture detection system .

Material requirements are given below :-

• MOISTURE SENSOR
• ARDUINO
• GREEN LED
• RED LED
• BRAEDBOARD
• JUMPER WIRES

Working

whenever the sensor detects moisture in the soil red LED glows otherwise green LED glows indicating no moisture .This can be used in gardens to make automatic watering system.

CONNECTIONS

ARDUINO

GND          =     -ve of green , red LED and

                          GND of moisture sensor

5V              =     VCC of moisture sensor

2                =      +ve of red LED

3                =      +ve of green LED 

4                =      OUT/DC of moisture sensor

CODE OF THE PROJECT :-

const int moisture = 4;
const int green = 3;
const int red = 2;

void setup() {
pinMode(moisture, INPUT);
pinMode(green, OUTPUT);
pinMode(red, OUTPUT);
}

void loop() {
if(digitalRead(moisture) == HIGH){
  digitalWrite(green,LOW);
  digitalWrite(red,HIGH);

}

else{
  digitalWrite(green,HIGH);
  digitalWrite(red,LOW);
 
}
}
