This document describes a remote health monitoring system using IoT (Internet of Things) and Arduino. The system collects health parameters like temperature, heart rate, and blood pressure from sensors and sends the data remotely to be viewed and analyzed. It notifies patients and doctors if any parameters exceed thresholds. The system is intended to help monitor patients outside of clinical settings and reduce healthcare costs. It discusses implementing the system using an Arduino microcontroller to process sensor data and an ESP8266 WiFi module to transmit data to a remote server. Results show the system can successfully post sensor readings online. The system provides a low-cost way to remotely monitor patients' health.
