Perancangan Alat Latihan Tinju Pengukur Jumlah Pukulan dan Kekuatan Pukulan Berbasis Internet of Things (IoT)

Maintaining physical health is crucial, and one way to achieve this is through regular exercise. Boxing is a suitable choice as it not only helps maintain fitness but also serves as self-defense, relying on punching skills. Previously, a device was developed to measure kick strength, but its results were only accessible via a localhost web interface, limiting access from other devices. This study aims to design a device for measuring the quantity and strength of punches in boxing, accessible anywhere via the internet. The device utilizes piezoelectric sensors with a web interface for measurement. In addition to piezoelectric sensors, it incorporates Arduino Mega, LCD, and ESP32. Sensor accuracy testing showed an average error rate 5.09% and 0% data transmission failure. Over 60 seconds in 30 trials, an average of 90 punches were recorded with an average punch strength of 800.
