Abstract

DESIGN AND DEVELOPMENT OF AN ARDUINO-BASED SYSTEM FOR MEASURING SOIL NUTRIENT

Ilo S. F., Nwali U. E.*

ABSTRACT

This project focuses on the development of a low-cost, Arduino-based soil nutrient monitoring system designed to measure essential soil nutrients nitrogen (N), phosphorus (P), and potassium (K) in real-time. Traditional soil testing methods are often costly, time-consuming, and inaccessible to smallholder farmers, leading to inefficient fertilizer use and soil degradation. To address these challenges, this system integrates an NPK sensor with an Arduino microcontroller to provide accurate, on-the-spot soil nutrient analysis. The system processes sensor data and displays results on an LCD screen or through a mobile application, enabling farmers to make informed decisions about fertilizer application. By offering a portable, affordable, and user-friendly solution, this project aims to optimize nutrient management, enhance crop yields, and promote sustainable agricultural practices. The system's modular design allows for future enhancements, such as integrating additional sensors for pH, moisture, and temperature, further improving its utility in precision agriculture.
