This study intends to design, build and implement a portable monitoring system of pulse rate and body temperature using Arduino microcontroller, equipped with SD Card, LCD screen, a 2.4 GHz Wi-Fi module for transfering data to the server. The author proposed designing a portable pulse rate and human body temperature monitoring system that measures data that can be accessed via the online web and android smartphone. This monitoring system consists of a sender system that combines a pulse sensor (Finger Sensor), temperature sensors, Arduino microcontroller, Mini LCD, SD Memory Card, Wi-Fi (2.4 GHz), and a receiver system. The receiver system consists of a database server using a Hosting server and an android smartphone with Java applications. Validation of this system was done by comparing to OMRON, ECG, Thermometer, and using different SSID when accessing the Wi-Fi network. Compared with OMRON, the error of this tool was 2.3%, 1.39% compared with ECG, 2% compared with Digital Thermometer, and also has a delay time of more than 1 second, so that should be improved in the future in order to be a real-time system.
