Some of the applications of Internet of Things are smart parking, smart home, smart city , smart environment, industrial places, agricultural fields and health monitoring process. One such application is in healthcare to monitor the patient health status Internet of Things makes medical equipment‟s more effective by allowing real time monitoring of patient health. We have a designed a system whic h is very helpful in monitoring & updating the patient health status in a graph report format to the doctor via PC or desktop. We have implemented a pulse monitoring for continuous pulse rate measurement for an hour/day is done by blood pulse sensor. Likewise body temperature, pressure, moisture, obesity has been noted using temperature sensor, pressure sensor, moisture sensor, flex sensor with the help of ADC converter. A Raspberry PI module picks up the sensor data and sends it to the network through WI-FI and hence provides real time monitoring of the healthcare parameters for doctors. These data can be accessed anytime by the doctor. The proposed system of the project is to report a clear notification of patient database health status in graphical form to the doctor side. Keywords-Internet of Things, health monitoring process, ADC converter,Raspberry PI,WI-FI. __________________________________________________*****_________________________________________________ I. INTRODUCTION In today‟s era, health problems are increasing day-by-day at a high pace. The death rate of 55.3 million people dying each year or 151,600 people dying each day or 6316 people dying each hour is a big issue for all over the world. Hence it is the need of hour to overcome such problems. We, therefore, proposing a change in wireless sensors technology by designing a system which included different wireless sensors to receive information with respective human body temperature, blood pressure, moisture, obesity, heart rate etc. that will be undoubtedly further transmitted on an IoT platform which is accessible by the user via internet. An accessible database is created about patient‟s health history which can be further monitored & analyzed by the doctor if necessary. The data storage can be saved on the server permanently or can be reset via the software. This paper proposes a health monitoring system which is capable of detecting multiple parameters of our body such as blood pressure, temperature, heart rate & further transmitting this information on an IoT server through 2G/3G/4G technologies. Also in case of emergency, automatically generating alerts will be sent to doctors if any unusual activity is detected by or near the patient. Satisfactory work is done in health monitoring by using raspberry pi as well as IoT, but this paper gives embedded concept of both the platform. By using combination of these, the proposed structure will be more effective. In this paper, we investigated recent papers related to health monitoring systems & IoT. Challenges in IOT:  Managing device diversity and interoperability: In the connected health domain, a variety of devices, instruments and equipment from device vendors andOEMs, located in homes and clinics, will connect to backend databases via aggregation devices located at the site. Aggregation devices are dedicated device gateways, home routers, smartphones and PCs, and their network is often referred to as the Peripheral Area Network (PAN). Commonly accepted standards of network interface are required between the devices and the aggregation device. Similarly, the interface between the aggregation device and backend medical records will be governed by regulations that mandate the use of certain approved standards and certification. Examples of standards in use in PANs include Continua Alliance Bluetooth Profiles and the ISO/IEEE 11703-20601 Optimized Exchange protocol¹. An emerging problem today is that there are still many vendors who do not support these standards in their products, thus leading to significant interoperability issues and increased system integration costs.
