3. INTRODUCTION Health monitoring systems become a very important topic and an important research field today and developed for many applications such as military, homecare unit, hospital, sports training and emergency monitoring system. The vital parameters in health monitoring system consists of blood pressure, heart rate, oxygen saturation, body temperature and respiratory rate to find the present health status of the patient. Now the data are collected using special type of processors example ARM7(LPC2148) and sensors after which these processed data are transmitted and displayed on doctors or relatives android mobile phones and on the personal computers using wireless sensor networks (WSN) or wireless personal area network (WPAN) namely Bluetooth and ZigBee.

4. Abstract: Patient monitoring systems are gaining their importance and demanding mainly because it is difficult for the elderly population to take care fast. These systems use wireless technologies to transmit vital signs for medical evaluation. The aim of the project is to provide a better health care to people from house in more economic and pertinent friendly manner. But here our focus will be particularly on Biomedical sensors measuring Body Temperature, Pulse Rate Counter and oximeter

5. METHODOLOGY A.Patient Monitoring System Design and Implementation of Real Time Embedded Tele-Health Monitoring System is utilizing Team viewer software and low cost component to transmit ECG data for monitoring, diagnosis and patients care at a significantly low cost. The physiological parameters such as ECG, Pulse rate and Temperature are obtained and is being processed using ARM7 LPC 2148 controller and is displayed in a MATLAB graphical user interface and if any critical nature is found i.e. anything beyond the normal range then alert SMS will be sent to Doctors computer. Microcontroller Based Health Care Monitoring System Uses Sensor based Network for measuring the Blood Pressure reading, Heart beat rate or body temperature etc. The whole system is controlled by microcontroller ATMEGA8L. B. Data Transmission Scheme Data is to be transmitted to remote location as per our requirement which involves various ways of communication technologies such as ZIG-BEE, BLUETOOTH, GSM, and GPRS.

6. SYSTEM ARCHITECTURE A.Body Temperature sensor The body temperature can be measured by putting sensor in contact with the body. Sensor mainly uses is DS18B30 is used to measure the body temperature which can transform the temperature signal into the digital signal for computation. B. Pulse Rate Counter It measures the pulse rate of the body. Pulse rate of a body can be counted by change in blood flow in blood vessels thus the system uses IR led and IR detector. The process is that depending upon the heart beat the pulse rate also increase and thus the heart pumps more blood and hence if a finger is placed between the Led and detector then according to the light received by the detector the process works. C. Oximeter The device is used for measuring the oxygen concentration of the body. NOTE:- The pictorial view is given on the next page

8. Here we see the reading from the BLOOD PRESSURE sensor giving the systolic and diastolic pressure in the form of pulse waveforms

9. FIGURE shows different type of sensors placed in a body for measuring the different parameters (blood pressure, body temperature, glucose and insulin)

10. Two methods of OXIMETER i) Using TRANSMITTANCE ii) Using REFLECTANCE

11. NOTE:- Oximeter measures O 2 concentration of the body

12. D. Android Application Nowadays the Bio sense application displays the processed medical parameter on android mobile with valued and graphical form. Thus the data is transmitted to the patient’s relative or to the Doctor via wireless networks to their Smartphone or in pc.

13. FUTURE SCOPE The HOME BASED MONITERING SYSTEM or APPLICATION helps the doctor and the patient in both ways while they are remotely present from each other. The user only just need to have an internet access on his PC or Smart Phone for data accessing and communication purpose. Thus in future we can create and saves the patient’s database, if patient could come after 1, 2 years then doctor can treat the patient very well using this type of monitoring system. Research Works are still on their way for presenting and spreading this type of monitoring system throughout and thus will help for the betterment of the people.

15. CONCLUSION This system reduce costs by enabling in home monitoring of patients and eliminating the need for utilization of expensive facilities, and also reducing the need for transportation of patients to physicians and Medical centres specially for the aged people who will be specially benefited by this system.
