IoT Based Smart Healthcare System for Real Time Monitoring and Diagnostics in Bangladesh

With the increasing adoption of healthcare Overseeing systems globally, there arises a critical concern for the security and accessibility of such systems, particularly in nations lacking robust mechanisms for public health monitoring. This paper addresses the absence of a comprehensive healthcare monitoring system in Bangladesh by proposing an IoT based smart healthcare solution. The primary objective is to develop a wireless monitoring system utilizing mobile devices to Perpetually monitor vital signs and symptoms, providing real time data transmission over the internet. The proposed system integrates sensors, a data gathering device, a Control unit, and website to record, display, and monitor key physiological parameters such as temperature, heart rate, and electrocardiogram. Through field testing, the dependability and accuracy of the system have been confirmed, demonstrating its efficacy in measuring patient physiological data. Using the MQTT communication protocol, all data are transmitted wirelessly. By leveraging inexpensive Elements and innovative IoT technology, this embedded system offers a cost effective solution for healthcare monitoring, tailored to the context of Bangladesh. Consequently, this research contributes to bridging the gap in Civic health monitoring infrastructure and lays the groundwork for scalable and accessible healthcare solutions in resource constrained settings.
