Smart Healthcare Monitoring System Using MQTT Protocol

The Internet of things (IoT) is the emerging paradigm, which contains a vital amount of smart devices and smart objects are connected to the internet for communicating each other. In IoT devices are used in numerous fields which make humans day to day life more comfortable. These smart objects and devices are used to collect information from a sensor like collect temperature, blood pressure, sugar level, which are used in healthcare to evaluate health condition of a patient. This collected information uploaded into the cloud so that doctor will make an accurate decision and notify the caretaker or nurse. In this paper, pulse rate, body temperature.spos.body movement of patient and other parameters are measured and this measured data uploaded to the MQTT server. This system notifies the patient with possible precautionary steps to be practiced by them and it also suggests the patient with medical care and what patient has to do when any critical situation come. This system helps the doctor to monitor his patient from anywhere and anytime and it also helps the patient relatives to view patient health condition remotely.
