Abstract

Health monitoring system is commonly implemented to continuously track human health condition. Heart rate and body temperature are two important parameters to maintain a vital life. In this study, a wireless monitoring system by using Bluetooth low energy device called Bluno is developed to monitor both parameters. The entire system comprises of several parts which are heart rate sensor using photoplethysmography (PPG) and temperature sensor that are connected to Bluno, and a computer for a graphical user interface to display the measurement. The suitability of two different types of PPG sensors which are visible green light and infrared sensors for heart rate detection is also been compared in this study. The comparison was done on the skin of the fingertips and the result shows that both sensors give a similar heart rate reading when applied to the fingertips simultaneously. On the other hand, the temperature sensor is tested on the respondents to evaluate the time taken for the system to capture the right skin temperature. Based on the result, it shows that the temperature sensor needs about 35 second to read a stable body temperature.
