The recommended approach for addressing sleep apnea in infants involves the utilization of CPAP therapy. A
pivotal component of CPAP therapy is the inclusion of a humidifier, which serves to counteract potential hazards by
introducing humidified air. The purpose of this study was centered on developing a compact, portable model to assess
temperature and humidity parameters in CPAP humidifiers. The method utilized was the pre-experimental One Group Post
Test Design. The contribution of this research lies in its ability to measure temperature and humidity in the CPAP humidifier
using the SHT30 sensor. The sensor readings were processed using the Arduino Mega 2560 Pro Mini microcontroller. The
measurement data was presented on a 20x4 LCD screen and had the capability to be stored using an SD Card, alongside the
inclusion of a buzzer indicator on the tool. The results demonstrated that the highest error value for the temperature parameter
was 1.8%, while the lowest was 0.49%. The expected conclusion is that these findings can be implemented effectively to
assist operators in recording, measuring, and monitoring temperature and humidity in CPAP humidifiers and to facilitate
monitoring of sleep apnea treatment procedures.
