Abstract


The purpose of this study is to design and demonstrate how the Internet of Things-based human temperature and heart rate monitoring tool works using blynk. The process of making a temperature and human heart rate monitoring tool based on the Internet of Things begins with hardware design by connecting all components, namely, NodeMCU ESP8266, Base Board, Mlx90614, Max30100, Oled, Led, and Buzzer followed by software design on Arduino software and blynk application whose measurement results will be compared with the actual tool that is often used. This study uses 3 different objects that are measured 3 times for each object. With an average error percentage of 0.91% for body temperature and 2.90% for heart rate. After going through the process of hardware design and software design, it has succeeded in designing a temperature and human heart rate monitoring tool that can be monitored remotely using the blynk application and has been functioning properly and working according to its function.
