Abstract

Asthma is a chronic respiratory disease that requires regular lung function monitoring. This study aims to design and develop a respiratory function monitoring device in the form of a Peak Expiratory Flow (PEF) meter based on the ESP32 microcontroller and MPX5010DP differential pressure sensor. The device is designed to measure the user's maximum expiratory capacity and classify it into asthma risk zones (green, yellow, and red) by comparing the actual PEF value against the predicted value. In addition to displaying results on the OLED screen, this system integrates the Telegram application as a digital storage medium for measurement history, allowing users to monitor their medical test records periodically. Testing was conducted on 30 respondents with a data collection procedure of three repetitions to obtain the highest value. Validation was performed by comparing the developed device against the Rossmax PF120A standard device. The results showed a very high level of accuracy with a Mean Absolute Percentage Error (MAPE) of 4.91%. Bland-Altman analysis showed a mean difference (bias) of 1.26 L/min with all data points falling within the Limits of Agreement (LoA) range. These results prove that the developed device has valid clinical agreement and is suitable for use as an instrument for independent monitoring and storage of respiratory function data history.
