IoT based health care system architecture

Introduction:
A Smart IoT healthcare system revolutionizes patient care by seamlessly integrating advanced technologies into medical practices. Through interconnected devices, sensors, and data analytics, it enables real-time monitoring of patient vital signs. This system empowers healthcare professionals with actionable insights, facilitates remote patient monitoring.

Smart Health care System components

The system consists of three main parts viz. IoT sensors, cloud connectivity and MCU (Microcontroller Unit). There are various sensors used in Smart Health Care system. They are commonly used in healthcare monitoring systems to track vital signs, physiological parameters, and activity levels of patients, enabling remote patient monitoring, disease management, and preventive healthcare interventions. Information collected by Sensors from patients can be relayed to the cloud servers. Web portals or Mobile Applications read these cloud data and display useful parameters for medical professionals.

Following are the common sensors used in IoT Health Care system.
• Heart rate sensors : Maxim (MAX30100) is a pulse oximeter and heart rate sensor module used as non-invasive heart rate monitoring. Analog Devices AD8232 is n ECG sensor used for monitoring heart rate and cardiac activity.
• Blood Pressure sensors : Examples are Omron BP785N, UA-651BLE from A&D Medical.
• Temperature sensors : Examples are Texas Instruments devices such as TMP36 (nalag output) and TMP102 (digital output) as well as Maxim DS18B20 (digital temperature sensor)
• Movement and activity sensors : LSM series sensors from STMicroelectronics
• EEG sensors : Sensors from NeuroSky MindWave
• Respiratory Rate sensors : Maxim MAX30100, PureSAT SPOT sensors

Benefits or Advantages of health care System

Following are the benefits or advantages of health care System.
