Smart IoT-Enabled pH Strip Reader for Simple and Accurate Analysis of Cervical Mucous pH

Abstract

The pH analysis of cervical mucous plays a significant role in providing valuable health insights for women. Accurate measurement of this pH metric is crucial for effective tracking and monitoring of reproductive health. However, current methodologies often present challenges in terms of confusion in test strip readings and susceptibility to external factors such as light fluctuations. In this study, we propose a robust and simplified approach for measuring cervical mucous pH, leveraging the integration of Internet of Things (IoT) technology and TinyML. Our setup ensures accurate readings, minimizing ambiguity, and offering a reliable means for women to effortlessly monitor their cervical mucous pH. We conducted experiments to compare the accuracy of our device with human interpretation of universal pH strips. The results show our setup demonstrates superior accuracy compared to laymen's interpretations of universal pH strips with small increments in pH (0.5 pH difference). This methodology empowers women to gain deeper insights into their reproductive health, aiding in informed decision-making and improving overall well-being.
