This real time temperature and heart rate patient monitoring system is designed and developed to enhance the diagnosis of patients and the ability of medical personnel to monitor patients’ health state. Owing to increasing related heart diseases in both old and young populations, an accurate, affordable and portable electronic health management device such as that developed in this work is essential for taking preventive measures. The usefulness of the device cannot be overemphasized in situations where no doctor or clinic exists nearby, and patients are unable to perceive the true state of their health. The developed system consists of an Arduino UNO microcontroller unit, the transmission unit, display unit, and biosensors. The system measures heart rate and body temperature vitals simultaneously acquired and processed on the portable device in real time, and sends the acquired information through a text message to the medical practitioner’s mobile device, which ultimately enables prompt prescription. The developed system proves to be more affordable compared to some other developed health devices due to use of the easily available Arduino UNO board, ubiquitous smart Android devices, and low-price sensors. It also shows accurate and acceptable outcomes when compared with some other more traditional measuring devices.
