विभाग : FABLAB -Practice Work : Moisture sensor

I have practiced and learnt connectivity of moisture sensor with using LCD display.  After the connection, I tested the sensor in water and mud and took readings on serial monitor in arduino software.  I have realized connectivity of sensor and LCD and I have realized this sensor is very useful.

• Connections :

• Readings :

• Programming Code

#include <LiquidCrystal.h>

int SensorPin = A0;

int SensorValue = 0 ;

int soil;

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {

  pinMode(SensorPin, INPUT);

  

  lcd.begin(16, 2);

  lcd.clear();

  

  Serial.begin(9600);

  Serial.print("soil moisture sensor");

  }

void loop() {

  

   SensorValue = analogRead(SensorPin); 

   SensorValue = constrain(SensorValue, 485, 1023);//compare Max and Min Value

   soil=map(SensorValue, 485, 1023, 0,100);// Convert Analog Value into Percentage Form

   

   Serial.print(100-soil);

   Serial.println("%");

   lcd.setCursor(0,0);

   

   lcd.print("Moisture Sensor Value:");

   lcd.setCursor(0,1);

 

   lcd.print(100-soil);

   lcd.print("%");  

  

    

 

}
