1. The document describes a smart patient monitoring system that uses sensors to collect patient health data like blood oxygen levels, heart rate, temperature, and sound to detect movement.
2. The system sends data to the Ubidots IoT platform for visualization and alerts, and uses protocols like MQTT for messaging between devices.
3. Sensors are connected to an ESP8266 or Arduino board to transmit data via email, SMS, or LED to monitors for notifications if measurements go outside normal ranges or movement is detected, with the goal of remote patient monitoring.
