The study aimed to design a device that provides fast and accurate readings of heart rate with intensity settings for exercise, blood oxygenation, and rate of calories burned. The device is composed of one control unit, which houses the microcontroller and the GSM module, and is attached in the user’s body as a belt together with eight (8) 1.2V-1900mAh batteries as supply. A pulse oximeter sensor is then clipped on the user’s fingertip and an LCD display is mounted on the wrist. The study used both qualitative and quantitative methods of research to acquire the essential data. This study was developed using an experimental method and descriptive approach. The research evaluation results affirm that the device was fully functional. The evaluators were interested on the idea of a pulse oximeter being utilized outside the medical field with the combination of heart rate and calorie rate of burned features. With this device, athletes and even regular individuals can monitor their performance conveniently with the accuracy of comparable values.
