This paper presents the design and implementation of an Internet of Things (IoT)-based system for remote electro-cardiogram monitoring.

• 📡 IoT-Based Monitoring: The system enables remote ECG acquisition and visualization through an Internet of Things (IoT) architecture.
• 🫀 Signal Acquisition: ECG signals are captured using electrodes placed on the user’s limbs.
• 🎛️ Signal Conditioning: The analog signals are amplified and filtered using instrumentation amplifiers and bandpass filters to ensure high-quality readings.
• 🔁 Client-Server Communication: ECG data is transmitted using socket-based communication between an ESP32 and a Raspberry Pi.
• 🌐 Real-Time Web Access: Data is forwarded to a central web server, allowing real-time analysis and visualization of ECG signals via a browser.
• 👨‍⚕️ Remote Evaluation: Physicians can remotely monitor and assess patients' heart activity, overcoming geographic barriers.
