AGRI GUARD - Monitoring, Automating, and Sustaining your Crops

Abstract

Over the years, technological innovations have transformed multiple sectors, with agriculture emerging as a crucial field that demands modernization. Despite significant advancements in farming techniques, many small-scale farmers still rely on traditional methods that lack precision, leading to inefficientresourceutilizationandunpredictablecrophealth.Addressingthis challenge, Agri Guard presents an intelligent, sensor-based agricultural monitoring system that enhances soil health analysis and disease detection while optimizing water usage. This project integrates a soil moisture sensor to automate irrigation, ensuring that crops receive adequate water without wastage. A DHT22 sensor monitors temperature and humidity levels, enablingfarmers to assess environmental conditions that affect plant growth. Additionally, a CO?sensor detects changes in microbial activity, which can indicate the early onset of plant diseases, providing preemptive alerts. A GSM moduleactsasa bridgebetweenthefarmandthefarmer,sendingreal-timedataandalertsdirectlytoamobilephone,ensuringpromptactioncan be taken when necessary. By leveraging Arduino-based automation, Agri Guard eliminates the need for constant manual intervention, reducing labor costs while improving overall farm efficiency. The system’s ability to provide real-time monitoring and automated responses makes it a valuable asset for farmers seeking to optimize productivity and safeguard crop health with minimal effort. This solution aligns with the modern vision of smart agriculture, where technology-driven farming practices ensure sustainability, efficiency, and improved yields

Introduction

Agri Guard is an innovative, cost-effective smart farming solution designed to tackle agricultural challenges such as inefficient irrigation, undetected soil problems, and high energy consumption. It integrates automated irrigation controlled by a soil moisture sensor, real-time monitoring of temperature, humidity, and CO? levels for early disease detection, and a GSM module to send instant alerts to farmers. Powered by solar energy, the system operates independently of grid electricity, making it sustainable and suitable for remote areas.

Unlike many existing models that rely on complex IoT platforms and internet connectivity, Agri Guard uses an Arduino microcontroller for simple, affordable automation, making it accessible for small-scale farmers. It ensures efficient water use by automatically activating pumps when soil moisture is low and shutting off when optimal levels are reached, preventing over-irrigation. The CO? sensor helps detect microbial activity related to plant diseases early on, while temperature and humidity sensors monitor environmental conditions to optimize crop health.

Real-time SMS alerts via the GSM module enable farmers to respond promptly to changing farm conditions, improving productivity and reducing manual oversight. The solar-powered setup ensures continuous, eco-friendly operation even in power-scarce regions.
