Rancang Bangun Sistem Monitoring Laju Pernapasan Non-Invasif Berbasis Sensor Negative Temperature Coefficient Secara Real Time
Breathing is a vital indicator of a person's health. Real-time monitoring of respiratory rate can help detect potential respiratory disorders. This study develops a non-invasive respiratory rate monitoring system using a Negative Temperature Coefficient (NTC) sensor to achieve high-accuracy measurements. The NTC sensor detects temperature changes caused by breathing activity. The system is designed for comfortable and efficient patient monitoring without the need for invasive tools. Trials on nine respondents of different ages revealed variations in breathing patterns. Some had normal respiratory rates, while others showed very slow (bradypnea) or very fast (tachypnea) breathing. Respondents with respiratory rates of 30 BPM (1.3 years old) and 18 BPM (19 years old) had normal breathing. However, respiratory rates of 6 BPM (8 years old), 36 BPM (14 years old), and 24 BPM (53 and 70 years old) were classified as abnormal. The results show that the system can effectively monitor breathing and help detect respiratory disorders early, as well as provide a basis for further medical intervention.
