Moisture Detection and Automatic Irrigation by Sensor Based Solar Tracker System

摘要

In this study, we propose a simple but efficient, lowcost powerefficient embedded system for solar based off grid irrigation by orienting the solar panel towards the sun to provide the necessary power source in remote areas or in the irrigation field where it is not possible to provide change through a stable current supply.The Solar Panel is used for 5V supply charging. We used Soil Moisture Sensor to sense the soil's moisture conditions. A water pump is connected to switch on and off automatically, based on the moisture sensor values.When humidity the soil level reaches to low,the soil moisture sensor sends a signal to the microcontroller to start the pump using solar energy stored. At the same time, microcontroller sends message about pump status to mobile farmers using GSM. The microcontroller gets pump status, humiditycondition of the soil and humidity and temperature in the air or surrounding area and provides this information over a data acquisition instrument. The system can be used in various fields by regulatingthe necessary voltage including mobile phone charging, access drip irrigation,and weather data monitoring and irrigation facilities as well..
