Nowadays technology plays a major role in healthcare not only for sensory devices but also in recording and display device and also in communication. It’s important to monitor various medical parameters and post operational days. Hence the latest trend using IOT in Healthcare communication method is adapted. Internet of things serves as a catalyst and plays major role in wide range of healthcare applications. In this project the ATMEGA8 microcontroller is used to communicate to the various sensors such as temperature sensor and pulseoximeter sensor. Microcontroller picks up the sensor data and sends it to the webpage and hence provides real time monitoring of the health care parameters for doctors and data can be accessed anytime by the doctor. Controller is also connected with buzzer to alert the caretaker about variation in sensor output. The major issue in remote patient monitoring system is that the data as to be securely transmitted to the destination end and provision is made to access the data is allowed only for authorized user. The security issue is been addressed by transmitting the data through the Keyword which will be encrypted by standard Msg91 and the users/doctor can access the data by logging to the html webpage. During the time of extremity situation through GSM module connected to the controller, alert message is sent to the doctor. Hence provisional medication can be done by this system and it is efficient with low power consumption capability, high performance and time to time response.
