1) SOIL MOISTURE SENSOR

Soil moisture sensors measure the volumetric water content In soil.[1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant, or interaction with neutrons, as a proxy for the moisture content.

The relation between the measured property and soil moisture must be calibrated and may vary depending on environmental factors such as soil type, temperature, or electric conductivity. Reflected microwave radiation is affected by the soil moisture and is used for remote sensing In hydrology and agriculture. Portable probe instruments can be used by farmers or gardeners.

Soil moisture sensors typically refer to sensors that estimate volumetric water content. Another class of sensors measure another property of moisture in soils called water potential; these sensors are usually referred to as soil water potential sensors and include tensiometers and gypsum blocks.

2) ARDUINO UNO

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.

Arduino code

int WET= 3; 
int DRY= 2;  
int Sensor= 0; // Soil Sensor input at Analog PIN A0
int value= 0;

void setup() {
   Serial.begin(9600);
   pinMode(WET, OUTPUT);
   pinMode(DRY, OUTPUT);
   delay(2000);
}

void loop() {
   Serial.print("MOISTURE LEVEL : ");
   value= analogRead(Sensor);
   value= value/10;
   Serial.println(value);
   if(value<50)
   {
      digitalWrite(WET, HIGH);
   }
   else
   {
      digitalWrite(DRY,HIGH);
   }
   delay(1000);
   digitalWrite(WET,LOW);
   digitalWrite(DRY, LOW);
}
