Wearable ECG

This device aims to be a portable and effective diagnostic tool to algorithmically detect heart arrhythmia and log ECG data over time. The device utilizes a Sparkfun AD8232-based board that processes and sends ECG data to the microcontroller. The microcontroller is a XIAO ESP32-C3 board that can produce a wifi server and connect via Bluetooth. This allows the device to connect to an IOS or Android application that can access the ECG data in real-time and allow ease of use. The device utilizes an Oled display to show ECG information, battery level, and system status. Regarding energy supply, the device utilizes three 18650 batteries, with a BMS (battery management system) that regulates battery voltage and current to maximize overall battery health. For the microcontroller to read the battery level, a MAX17043-based fuel gauge reads the battery voltage for the microcontroller to monitor.
