Implementation of Internet of Things Devices for Calorie Monitoring in Cyclists

This research aims to design and implement an Internet of Things-based device that is used to combine speed and calories on a bicycle without requiring additional applications. This device is designed so that cyclists can stay focused on sports activities without having to interact with smartphones that could potentially reduce concentration. The developed system consists of a speed sensor, a calorie calculation module, and hardware that directly displays information through a 16x2 LCD screen. The research method includes the hardware design stage, sensor accuracy measurement, and system performance evaluation under various usage conditions. The results show that the device is able to display speed and calorie data with a sufficient level of accuracy, so it can provide relevant information to improve the quality of cycling activities. This research contributes to the development of Internet of Things technology in the fields of sports and health, especially in providing practical, safe, and efficient monitoring devices for users.
