Structure of Soil Moisture Sensing Electronic Irrigation System

Abstract

Appropriate environmental conditions are necessary for optimum plant growth, improved crop yields, and efficient use of water and other resources. Automating the data acquisition process of the soil condition allows plant growth with less labor requirement. This project on "Structure of Soil Moisture Sensing Electronic Irrigation system" is intended to create an automated irrigation mechanism that turns the pumping motor ON and OFF on detecting the moisture content of the earth. In the domain of farming, utilization of appropriate means of irrigation is significant. The benefit of employing these techniques is to decrease human interference and still make certain appropriate irrigation. The objective of this project is to design a simple, easy-to-install microcontroller-based circuit to monitor and record the values of soil moisture levels that are continuously modified and controlled to optimize them to achieve maximum plant growth and yield. This automated irrigation project brings into play an Arduino board ATmega328P microcontroller used is a low power, cost-efficient chip by ATMEL that is programmed to collect the input signal of changeable moisture circumstances of the earth via a moisture detecting system. An integrated Liquid crystal display (LCD) is also used for the real-time display of data acquired from the sensor and the status of the various devices. Also, the use of easily available components reduces manufacturing and maintenance costs. The design is quite flexible as the software can be changed at any time. It can thus be tailor-made to the specific requirements of the user This makes an efficient system for optimization of yield with minimum use of water. This system is also economical, portable, and user-friendly.
