This document describes a proposed smart irrigation system using solar power for the Ministry of Uttarakhand. The system would use soil moisture, humidity, and temperature sensors connected to an Arduino board to monitor field conditions. If the sensors detect conditions are below minimum thresholds, it would trigger the mobile app to notify the farmer. The farmer could then use the app to control a relay and solar pump to irrigate the field automatically. The system aims to use solar power to irrigate fields based on real-time sensor data to help farmers and support agriculture development.

3. SOLUTION APPROACH
First solar panel will store energy in the battery. When the system starts it will go into
senses . These senses will measure the moisture , humidity and temperature and transfer the
collected data to Arduino.
 Arduino will process and give data to the mobile app. If the moisture , humidity and
temperature are less than their minimum value then this will indicate on the mobile app and
the farmer will know about the condition of the field.
The information to turn on the irrigation system on the mobile app will pass to Arduino
and then to the relay and then water will be supplied in our irrigation field.

When the rainy season will increase, automatically humidity will also increase and
the condition will not be fulfilled, the buzzer will start ring continuously and we will
have to turn off the power supply and turn off the buzzer.
