Design Implementation Low-Cost IoT-Enabled Smartwatch Project Details
| Abstract |
This project presents the design, implementation, and validation of a low-cost, Internet of Things (IoT)-enabled smartwatch designed for continuous, real-time monitoring of vital physiological parameters. To address the high cost of commercial health-tracking wearables, the system integrates a MAX30102 pulse-oximetry and heart-rate sensor, a DS18B20 digital temperature sensor, and an ATmega328P microcontroller. Peripheral components include a DS3231 real-time clock, an HC-06 Bluetooth module for wireless data transmission, and an SSD1306 OLED display for local visualization. Power management is achieved using a three-stage power tree comprising a TP4056 charge controller, an MCP1700 low-dropout regulator, and MOSFET-based peripheral load switching to optimize battery life. The firmware, developed within the Arduino environment, implements
a peak-detection algorithm for heart-rate estimation, a ratio-of-ratios method for calibrated SpO2 calculation, and a signal-quality gate to filter out motion artifacts and unreliable readings. This resource provides comprehensive implementation support, component guidance, and structural review for undergraduate engineering students seeking to develop, calibrate, and validate wearable biomedical devices against medical-grade reference instruments.
