Reading the Qur’an as an active spiritual vocalization activity can influence physiological responses, particularly oxygen saturation (SpO2) and heart rate. This study aims to design and evaluate a detection device to measure the effect of active Qur’an recitation on SpO2 and heart rate using a MAX30102 optical sensor integrated with an Internet of Things (IoT) system. The system consists of a MAX9814 sound sensor, ATmega328 microcontroller, RTC DS3231 module, microSD storage, LCD display, and real-time monitoring via the Blynk application. The experiment involved five healthy students (3 males and 2 females, aged 20–22 years) from the Diploma Program in Physics, Universitas Sumatera Utara. Measurements were conducted for five minutes under three conditions: before, during, and after Qur’an recitation. The results show a significant decrease in heart rate by 12.08% (p < 0.05) and a significant increase in oxygen saturation by 1.69% (p < 0.001) after recitation. The system achieved accuracy levels with 7.06% error for heart rate and 0.67% for SpO2. This study demonstrates the novelty of integrating optical sensing and IoT-based real-time monitoring to analyze physiological responses to active Qur’anic recitation.
