A.Haripriya, K.Sandya, T.Esha, P.Pooja, A.Pallavi 02 7(1) Healthcare is one of the most critical sectors where continuous patient monitoring can play a significant role in saving lives Traditional health monitoring systems often require patients to be physically present in hospitals leading to delays in diagnosis and treatment during emergencies To address this limitation this work proposes an IoTbased Health Monitoring System using Raspberry Pi that enables realtime remote monitoring of vital signs The system employs biomedical sensors such as heart rate temperature blood pressure and SpO sensors which are interfaced with the Raspberry Pi microcontroller These sensors continuously capture patient health parameters and transmit the data to a cloud server or web application using WiFiThe Raspberry Pi acts as the processing hub collecting analyzing and forwarding sensor data for visualization and storage Doctors and caregivers can access this information remotely via a secure web dashboard or mobile application allowing for early diagnosis and timely medical intervention In critical situations the system can automatically generate alerts or notifications via SMSEmail to medical professionals and family members ensuring rapid responseThe proposed IoTenabled solution provides a lowcost scalable and efficient health monitoring framework that reduces hospital visits supports remote patient care and improves overall healthcare accessibility By combining Raspberry Pi IoT and cloud computing this system contributes toward the development of smart healthcare solutions paving the way for personalized and preventive healthcare services in both urban and rural areas Copyright (c) Journal of Science Engineering Technology and Management Science.
