Development of smart health monitoring system using Internet of Things

Abstract

In this modern world, automation plays a vital role. It creates influences in the medical field. It reduces human work and provides more benefits for humans. Automation provides more accuracy than manual methods. The patient’s health monitoring system is one of the automated systems to measure various health-related physical parameters of the patient. The medical field are growing by using IoT platforms. It helps to get information about the patient in a short period of time. The basic physical parameters to be measured are temperature, pressure, pulse rate, glucose level and oxygen level. Temperature is measured using the LM35 sensor (temperature sensor). A pressure sensor is used to monitor pressure (digital sphygmomanometer). Pulse rate is measured by a heartbeat sensor (LM358 OPAMP). Pulse oximetry is used to measure the oxygen content in haemoglobins. A glucometer is used to measure the blood glucose level. In this Node-MCU is used as a microcontroller. This Wi-Fi module helps us to send the measured physical parameters to the cloud and Google sheets. If there is any discrepancy in the measured value, an alert message (E-mail or SMS) will be sent to the doctor and to the patient’s relative.
