The main objective of this prototype is to provide motor ON or OFF information to the farmers, which helps in saving water quantity and money. The entire prototype is controlled by using Arduino UNO microcontroller, which gives interrupt signal to the motor pump. Soil moisture sensor is connected to digital port through Analog and Digital comparator. Whenever there is a fluctuation in soil moisture sensor senses the changes happening in soil and send interrupt signal to the Arduino and thus the motor pump is activated or deactivated depend upon the changes happening in the soil.
