    Automatic Irrigation System Using Arduino

    Automatic Irrigation System Using Arduino

    In this project, we will make an automatic irrigation system using Arduino microcontroller. Automatic Irrigation system monitors the soil moisture and depending on set points turns on/off the pump which is connected to the relay. This way you can keep soil moisture to a set point.

    This system automatically waters the plants when we are on vacation. As we are setting the soil moisture level, we need not worry about too much of watering and the plants end up dying anyway.

    The project is designed to develop an automatic irrigation system which switches the pump motor ON/OFF on sensing the moisture content of the soil. This project requires Arduino board having inbuilt ATMega328
    microcontroller.

    An automated irrigation system will minimize the excess wastage of water and the labor and other overheads.

    In the field of agriculture, use of a proper method of irrigation is important. The advantage of using this method is to reduce human intervention and still ensure proper irrigation.

    Components Required for this Project

    You need the following items to complete this project.
    1. Arduino Uno
    2. Soil moisture sensor
    3. 16×2 LCD
    4. 1K, 220E Resistors

    7. Switches

    Automatic Irrigation System Circuit

     

    Automatic%2BIrrigation%2BSystem%2BUsing%2BArduino

    LCD displays the current moisture level and set point. The setpoint can be adjusted using push buttons. Connect relay output to the water pump. Put soil moisture tip in the soil where you want to maintain soil moisture.

    Working of Automatic Irrigation System

    The soil moisture sensor senses the moisture present in the soil and gives the output to Arduino. The output of the sensor will be from 0-1023. The moisture is measured in percentage, therefore we should map these values to 0-100.
     
    Whenever the moisture value is lower than the value we have set inside our code as the threshold value, the relay will turn ON and the valve will turn open and whenever the moisture value is lower than this threshold value, the relay will relay will turn OFF and the valve will get closed.
