Abstract
This study aimed to improve efficiency and reduce costs associated with soil nutrient analysis for farmers. A device called SoilMac.pH, utilizing an Arduino Mega 2560 microcontroller and TOSHIBA TCD1304AP CCD Linear Sensor, was developed to measure soil macronutrients (Nitrogen, Phosphorus, and Potassium) and pH levels. Spectroscopy and the Beer-Lambert law were employed to classify these parameters accurately in Philippine farmlands. The results were presented in a printed form, including nutrient and pH level calculations, along with fertilizer recommendations. This project particularly benefits farmers in remote areas, providing rapid results within one to two hours, eliminating the need to visit regional soil test centers and endure lengthy waiting periods. The study focused on identifying soil macronutrients and pH levels for rice crops, achieving a 95% accuracy rate.
