Abstract

PH level is a quality parameter used in several areas such as agriculture, chemistry and health. There are different ways to measure pH, including the use of indicator strips, whose chemical properties provide a change in the color of the paper depending on the acidity level of the substance in which it is immersed. This paper presents the construction of a mobile Android application capable of identifying pH on an test strip using image processing.
