IoT Based Health Monitoring and Automation System for Hospital

IoT Based Health Monitoring and Automation System for Hospital

Project Overview

The IoT Based Health Monitoring and Automation System for Hospital is a smart healthcare solution designed to continuously monitor patient health parameters and automate hospital facilities using Internet of Things (IoT) technology. This system enables real-time health data collection, remote monitoring by doctors or hospital staff, and automated control of medical and electrical devices, thereby improving patient care, safety, and operational efficiency.

Objectives

• To monitor vital health parameters of patients in real time

• To enable remote access to patient data using mobile or web applications

• To automate hospital equipment such as lights, fans, and alerts

• To reduce manual monitoring effort and human error

• To provide quick alerts during critical health conditions

System Working Principle

The system uses multiple biomedical and environmental sensors connected to a microcontroller or IoT-enabled development board. These sensors continuously collect patient health data such as body temperature, heart rate, and oxygen level. The collected data is processed and transmitted to a cloud server via Wi-Fi or GSM.

Doctors and hospital staff can view live data on a smartphone or web dashboard. If any parameter crosses a predefined safe limit, the system automatically triggers alerts, notifications, or emergency actions such as activating alarms or sending SMS alerts.

In addition, hospital automation features allow remote or automatic control of devices like lights, fans, and ventilation systems based on patient condition or room environment.
