IoT-enabled Health and Environment Monitoring System

Abstract

The integration of Internet of Things (IoT) technologies has revolutionized personal health monitoring, especially for athletes who require precise and continuous data for performance optimization and well-being. In order to gather, process, and send real-time physiological and environmental data, this study presents an IoT-enabled health and environment monitoring system specifically built for athletes. Two microcontrollers are included in the device: an ESP8266 that processes heart rate and SpO2 data from the MAX30100 sensor and an ESP32 that handles data from other sensors. A 16x2 I2C LCD shows environmental characteristics such as temperature, humidity, light intensity, and air quality. The Blynk app visualizes a complete dataset that includes pressure, temperature, humidity, light intensity, heart rate, SpO2, air quality, sound intensity, and ECG signals for easier access and analysis. Key components include the MAX30100 for heart rate and SpO2, DHT11 for temperature and humidity, BMP280 for pressure and altitude, BH1750 for light intensity, MQ2 for air quality, KY038 for sound intensity, AD8232 for ECG monitoring, and a 16x2 LCD for on-site data visualization. Two 3.7V batteries that are controlled by a 2S BMS (20A) unit and a 7805 IC ensure steady operation of the device. It is perfect for athletes, coaches, and fitness fanatics because to its modular design, which guarantees scalability, and its emphasis on price and ease of implementation. Through the use of IoT, this system improves training, safety, and general health by allowing athletes to keep an eye on their surroundings and physiological performance.
