Internet of Things (IoT) is used to communicate two or more object or devices over the internet without interaction of the human. In the present days the IoT is becoming more and more popular because of its wide variety of uses in different domains such as home automation, smart city monitoring, Transport and logistics, Smart Environment, Health Care, Smart Agriculture, Medical field, Energy Management, Retails, Marketing field etc. In this paper focus is made on Health care Domain. Health Monitoring using Node-Micontroller-Unit(MCU) is proposed to check the patient health condition dynamically without visiting the hospital. In proposed work many smart devices are used to collect the heart rate, body temperature, sugar level. from the human body. If any variance above or below normal threshold is found in human body such as heart rate, temperature and sugar level then this system will send a sms to his/her family doctor/hospital, it also shares the current location of the person as it is very useful for them to track the patient.
