3. Introduction  The need for health consciousness has increased in the recent past and so is the need to monitor vital parameters.  However, a number of monitoring devices are complex and cannot be used in our homes because of their size and portability.  The cost involved is huge.  The time gap between occurrence of an illness and the provision of treatment is high, due to transportation delays and such.

4. Our solution  In order to solve this problem, we have integrated all these features (ECG,body temperature etc..) on to a single platform with extended features such as gsm,Wi- Fi and cloud accessibility with Arduino as their head.  This platform can be used by everyone and is highly portable.  Helps in maintaining body vital conditions to some extent.

5. List of sensors  Airflow sensor (breathing)  Body temperature sensor  Electrocardiogram sensor (ECG)  Glucometer sensor  Patient position sensor (Accelerometer)  Blood pressure sensor (sphygmomanometer)

6. The head  Microcontroller -ATmega328  Operating Voltage - 5V  Input Voltage -7-12V  Input Voltage (limits)6-20V  Digital I/O Pins14 (of which 6 provide PWM output)  Analog Input Pins -6  DC Current per I/O Pin - 40 mA  DC Current for 3.3V Pin - 50 mA  Flash Memory - 32 KB (ATmega328) of which 0.5 KB used by boot loader  SRAM2 KB (ATmega328)  EEPROM - 1 KB (ATmega328)  Clock Speed - 16 MHz

8. GSM module  It is used to alert the hospital when vital conditions are going below a certain level.  It also sends a message to the doctor of the values being recorded by the sensors.(when net connectivity is not present),by this the doctor can have a tab on the patient continuously  It uses the SIM900 and can be easily interfaced to the Arduino

9. Connectivity  For cloud storage, we are making use of the Ethernet shield by which the Arduino is connected to the internet.  The WiFi shield can be used to connect wireless to the internet  This shield can be directly stacked in top of the Arduino.  The Ethernet controller is Wiz5200

10. Arduino to the net  Near Bus is a Cloud Connector that allows you to fully integrate in the MCU platforms (like Arduino, OpenPicus, etc.)  The Arduino will connect directly to the Near Hub server through the internet access router and you will be able to control it from your web browser.  The Arduino memory is mapped into the cloud (mirroring process)

11. Display  In order to display the ECG waveforms, body temperature values and other vital parameters we use a GLCD(graphic lcd) instead of a normal 16*2 lcd module.  It can easily interfaced to the Arduino.

12. Basic idea (temperature sensor)  In order to sense the body temperature, we are using a DHT11 temperature sensor instead of LM35 because of parameters such as accuracy.  It can be easily interfaced to the Arduino.  These values can then be displayed on the GLCD or can be transported to the cloud via the Ethernet shield using Near Bus

13. Connecting to arduino

14. The code  #include  // the setup routine runs once when you press reset:  void setup() {  Serial.begin(115200);  }  // the loop routine runs over and over again forever:  void loop() {  float temperature = eHealth.getTemperature();  Serial.print("Temperature (ºC): ");  Serial.print(temperature, 2);  Serial.println("");  delay(1000);// wait for a second  }

15. The results

16. ECG  The ECG is used to used to assess the electrical and muscular functions of the heart.  The electrodes can be interfaced to the Arduino and the graph can be obtained on a GLCD  If the graph seems to be abnormal then then the gsm alerts the hospital and necessary action is taken

18. Position of electrodes

19. Breathing rate sensor  We measure the temperature of the air directly outside a person's nostril. As the user breathes in, cool air gets sucked into the nose, lowering the temperature on the sensor. As the user breathes outs, warm air from inside the person comes out, increasing the temperature. By tracking this temperature we can determine the user’s breathing rate.

21. The code  #include  // The setup routine runs once when you press reset:  void setup() {  Serial.begin(115200);  }  // the loop routine runs over and over again forever:  void loop() {  int air = eHealth.getAirFlow();  eHealth.airFlowWave(air);  }

22. The results

23. Blood glucose meter  The first step to measure glucose in the blood is to convert the glucose concentration into a voltage or current signal.  The sensor uses a platinum and silver electrode to form part of an electric circuit where hydrogen peroxide is electrolysed. is produced as a result of the oxidation of glucose on a glucose oxide membrane. The current flowing through the circuit provides a measurement of the concentration of hydrogen peroxide, giving the glucose concentration.
