Affordable Smart ECG Monitoring Using Arduino and Bluetooth Module

The Affordable Smart ECG Monitoring System is designed for real-time cardiac monitoring with enhanced alert capabilities. The system uses an Arduino mega as the main controller, interfacing with an ECG sensor to monitor heart activity and a temperature sensor to track body temperature. Readings are displayed on an LCD screen, while a buzzer alerts the user of abnormal conditions. In addition, a GPS module tracks the patient’s location, and a GSM module sends an alert message with the location details to a caregiver or medical professional when any abnormality is detected. Data can also be transmitted via a Bluetooth module to a smartphone or computer for continuous monitoring. This low-cost, portable system ensures early detection of cardiac anomalies and rapid emergency response, making it suitable for home use, elderly care, or clinical settings.
