Keywords: Bluetooth, Arduino, Sensors, Android Application, Low power, Patient Monitoring, Healthcare. 1. Introduction The demand of excellent healthcare systems increasing day by day. Designing these kindof systems which are helpful for society and easily access by less fortunate people. Furthermore, in hospitals, generally doctor needs to move from one patient to another for checking them. Hence it may not feasible for them to monitor a patient again and again. There would be more circumstance when there is large number of patients. To overcome from this issue the system proposed which measures heart rate and temperature of a patient and remotely get status. The patient can monitor himself and certain significance will lead to an initial treatment if needed. This experimentation will keeps person healthy and monitored. It helps the patient to test and improve the health. One of the restrictions of the proposed health monitoring system is that it will measure the data in the specific area. It is not possible for experts to monitor patient from out of coverage area.the proposed system basically works on Arduino environment with the respective sensors. The implementation of both hardware and software through the respective modules. The sensors result will display on the Arduino software environment. The Bluetooth module will send the analyzed data between these components. The person or an expert gets periodically updates of result by displaying it to the android mobile application. The system consumes low power energy. It designed as per low cost and portable. Figure1Overview of Monitoring System 2. Related Works 549

2 SalomiS. Thomas et al.implements that the digitally working on variety of sensors and allow a person to measure their mean arterial pressure in one minute. At a certain interval of time alert would be generated and displayed on the screen. Khalifa Al Sharqi et al. proposes in the field of wireless technology. The person should wear the sensors and then it would send and receive the data using Zigbee. Those data readings would get displayed on Labview software. Qingchao Gong et al. implements that the pulse signal framework in view of Bluetooth transmission is another arrangement that used to take care of the demand of high automation and helpful drug. The system is minimal in cost, highly reliable, basic structure and free in transmission. The pulse motion is gathered through pulse sensor, and after that send to microchip for ongoing preparing, compute related information furthermore, show critical data on PC administration platform. The pulse signal is beneficial health monitoring for humans. Prasad Kumari Nisha et al. implements and displays the usage of heart rate checking interface including ease Arduino board and other effectively accessible assets. This project was effectively executed and the yield showed on the visualizer. Heart beat for one moment is counted and the yield is shown on the LCD. Information transmission from Arduino to the cell phone through Bluetooth was likewise accomplished. As per the proposed interface specialist does not should be available while checking the heart rate. The specialist can get the heart rate of patient remotely. 3. System Architecture The proposed system is to obtain the parameters from various sensors such as temperature sensor and pulse rate sensor. These sensor parameters are analysed by implementing with the Arduino..The integration of sensors and Bluetooth module with Arduino is likewise formed that it will transmit every signal to the doctor or patient itself. The inputs given by the patient on the sensors are displayed on software serial monitor of Arduino IDE environment or on android application. These accurate parameters of an person are fetched and transmitted by the Bluetooth module. The Bluetooth module transmits the signals and gets display on android device Bluetooth list for connection. Figure2 System Architecture The option for accessing the parameters is not for all only those person access these parameters who know the password which has been set to Bluetooth module. For connecting the android device to the module, a person must enter the password which has been set in Bluetooth module. So that an unauthorized person will not able to access the values. The android device is start receiving the data through Bluetooth and displayed on the application. The doctor must be within the range of Bluetooth module so that they will stay connected and fetch the readings on his/her application. The patient can choose to be self-monitored in order to improve his/her health. The smartphone have user-friendlygui so that the elderly patient will also easy to access it. Therefore, a visual display will be added so that a patient get periodically monitored and updated by his/her health status. 4. System Design and Implementation The proposed system has implemented on Arduino Uno where all interface takes place on bread board. There are three components temperature sensor, pulse rate sensor and Bluetooth module which connected to 5 volts of Arduino. So that the Arduino supplies the 5 volts to the breadboard by which all those pins which needed 5 volts are connected. Although the Ground pin also connected 550 to breadboard through jumper wires. The analog pins are used to read the values from specified pins.
