Alat Deteksi Gejala Tuberkulosis Paru Menggunakan Sensor Fusion melalui Hembusan Napas Secara Noninvasive

Abstract

The Lung Tuberculosis Symptom Detection Device has been successfully designed using Sensor fusion through breath analysis via Non-Invasive. The objective of this device design is to create an effective instrument for early tuberculosis detection through breath odor or VOCs analysis and to develop a practical, portable medical check-up device based on Sensor fusion technology. This device utilizes a combination of three gas Sensors, including TGS 813, TGS 822, and TGS 2602, as research parameters by analyzing changes in voltage patterns. The working principle starts with collecting breath samples from symptomatic and non-TBC patients, which are stored in a Breathing Bag and then inputted into the device. The testing was conducted using Non-Invasive by collecting data from 12 confirmed TBC patients based on previous medical examinations and 4 healthy individuals confirmed to be TBC-negative. The analysis results from the Sensor fusion combination indicated a significant difference in voltage patterns between symptomatic TBC patients and TBC-negative individuals using The sensors TGS 813, TGS 822, and TGS 2602 exhibit different voltage pattern ranges between TB-symptomatic patients and TB-negative individuals. In TB-symptomatic patients, the TGS 813 sensor generates a voltage of 137–147 mV, the TGS 822 sensor ranges from 395–530 mV, and the TGS 2602 sensor ranges from 150–250 mV. Values outside these ranges are categorized as TB-nonsymptomatic individuals. These identification ranges indicate significant differences that can be used as references for TBC detection. These voltage pattern differences can serve as significant indicators for distinguishing symptomatic TBC patients from TBC-negative individuals for tuberculosis detection.
