This project focuses on the development of a heart attack detection and heart rate monitoring system utilizing Arduino and Internet of Things (IoT) technology. The system integrates sensors such as pulse sensors and electrocardiogram (ECG) modules to continuously monitor the heart rate and detect any anomalies. The data collected is processed using Arduino, which serves as the system's central microcontroller, and then transmitted to a cloud-based platform via IoT for real-time monitoring and analysis. Alerts can be sent to the user, caregivers, or medical professionals in the event of an irregular heart rate or potential heart attack. This approach enhances patient safety and provides a timely response in emergencies by leveraging IoT for remote monitoring and data storage, offering a comprehensive and accessible solution for cardiovascular health management.
