    Healthcare is one of the least funded sectors in Bangladesh and many other similar developing countries. There is no health coverage and health insurance is almost non-existent. Thus, people living in rural and remote areas do not have access to proper healthcare and when they do, it is too expensive. The aim of this research was to develop a real-time health monitoring system that is cheap, easy to use and accessible by both doctors and patients. The system consists of several Internet of Things (IoT) based sensors connected to an Arduino microprocessor, which thus measures the body vital signs of the patients. The measured readings are then transmitted to an android application on a smartphone via a Bluetooth module. The sensors are connected to analog inputs. These sensors measure analog data which is amplified by the microprocessor after being sorted. Doctors can also carry out the diagnosis of ailments using the data collected remotely from the patient. An Android based mobile application that interfaces with a web-based application is implemented for efficient patients-doctors dual real-time communication. The android application, which is connected to a mySQL database, updates the said database, which in turn updates and displays the readings on a website accessible by both doctors and patients. The health monitor was initially tested using an Arduino Integrated Development Environment (IDE) monitor and one single user. Once initial simulations were successful, it was tested on a sample size of 5 more patients. In the end, the testing of the wireless health monitor produced successful results that measured patient vitals with a high level of accuracy.
