Vital Signs Devices function to detect vital signs from the human body, such as body temperature, blood pressure, heart rate, and blood oxygen levels. These vital signs provide us information whether our body is healthy or not. This vital sign monitoring device used Arduino Node MCU ESP32 as the data processor integrated with a Wi-Fi module, thus, supporting Internet of Things (IoT) application system. It is connected to an Android smartphone and can display measurement data in real-time. There are three sensors used, namely skin temperature sensor, Nellcor Saturation Partial Oxygen (SPO2) sensor and NIBP sensor that can display parameters such as SPO2, NIBP, heart rate, and body temperature in real-time. Vital Sign Simulator was used to test the SPO2, NIBP and heart rate parameters. Body temperature parameter was tested using warmed water medium in a water bath. The results of normal SPO2, NIBP, heart rate, and body temperature measurement showed fairly small differences.
