Secured Smart Healthcare Monitoring System Based on IOT

Technology plays the most important role in healthcare not only for sensory devices but besides in communication, recording and display device. It is very important to monitor various medical parameters and post operational days. Therefore the latest development in Healthcare communication method using IOT is adapted. Internet of things serves as a catalyst for the healthcare and plays prominent role in wide range of healthcare applications. In this project the PIC16F877A microcontroller is used as a gateway to communicate to the various sensors such as temperature sensor, Respiration sensor, Blood Oxygen level and heart beat sensor. The microcontroller picks up the sensor data and sends it to the network through IOT and hence provides real time monitoring of the health care parameters for doctors. The data can be access anytime by the doctor. The controller is in addition connected with buzzer to alert the caretaker about variation in sensor output. Other than the main issue in remote patient monitoring system is that the data as to be securely transmitted to the destination end and provision is made to allow only authorized user to access the data. The security problem is be addressed by transmitting the data through the password protected internet which will be encrypted by standard AES128 and the Doctors can access the records by logging to the html webpage. Next to the instance of extremity situation alert message is send to the doctor through IOT connected to the controller. For this reason quick provisional medication can be easily done by this system. This system is capable with low power consumption capability, easy setup, high performance and time to time response.
