IoT-based Patient Monitoring System through Online Cloud and ECG Sensor

The Internet of Things (IoT) is revolutionizing healthcare by enabling remote patient monitoring. An IoT-based patient monitoring system is the main focus of this study that uses an electrocardiogram (ECG) sensor, a wire thermometer sensor, and a DHT11 sensor. The objective of the system is to continuously monitor the ECG signals of patients, monitor patients' body temperature and patients' room temperature and humidity, and transmit them wirelessly to a cloud-based server for real-time analysis. The proposed system comprises an ECG sensor, a one-wire thermometer sensor, a DHT11 sensor, a microcontroller, and a wireless communication module. The ECG sensor captures the electrical signals generated by the heart and converts them into digital signals. The DS18B20 sensor measures patients' body temperature, and the DHT11 sensor monitors room temperature and humidity. The microcontroller processes the digital signals and transmits them to the cloud-based server through the wireless communication module. The smartphone Apps take patients' records from the cloud, analyze the ECG signals, and generate necessary suggestions if any abnormalities are detected.
