In intensive care units patient’s heart beats, temperatures, blood pressure etc. are continuously monitored. When patients gets well and come back to home from hospital might get infected with a new disease this may cause his death. So in many cases, patients are released from hospital but still they are strongly advised to be under rest and observation for some period of time. These devices eliminate the need for the patient to visit a doctor. Remote collection of patient’s data sending through SIM 300 modem is possible. These devices also allow the doctor to communicate feedback to the patient remotely, using SMS alerts. In this system we take vital physiological data of a user and send the data together to an android O.S based mobile for processing and may trigger necessary SMS action.

INTRODUCTION        To implement the remote health monitoring system using android operating system. After discharged from ICU patient has to make frequent visits to their doctor to get their vital signs measured. Regular monitoring of vital signs is essential as they are primary indicators of an individual’s physical well-being.             In this system physiological data of a patient is taken and through SMS it is sent to a Android based mobile for processing. In this application written on android based mobile will send back SMS to patient on the unit where SIM 300 is connected. This system gives great freedom to users. Here SIM 300 GPRS/GSM modem is used for sending data and receiving data via SMS. Android operating system is an open platform and hence the cost of the mobile monitoring system becomes less.                                     II.PATIENT SIDE UNIT  A. LPC2148 ARM CONTROLLER  We are using LPC2148 which is an Advanced RISC Machine. It is a 32 bit controller which is having Von Neumann architecture. It has a 3 stage pipelining and a memory of 4GB along with two UARTs. It operates at a speed of 60 MHz and also due to its interrupt priority feature. It consumes less power and is used in applications were miniaturization is of paramount importance. A real-time clock which operates at 32 KHz is in-built in the controller.         Fig 1. Configuration of patient-side device  B. BODY TEMPERATURE           The LM35 is precision integrated-circuit whose  output is linearly proportional to the Celsius temperature. The scale factor is +10.0mv/°c. Hence temperature is equal to Vout*(100°C/V).The voltage from LM 35 is converted to digital format using ADC of ARM controller. This digital value is used to send via SMS after proper conversion.   C. HEART BEAT          The sensor consists of a super bright red LED and light detector. The LED should be super bright as the maximum light must pass spread in finger and detected by detector. When the heart pumps a pulse of blood through the blood vessels, the finger becomes slightly more opaque and so less light reached the detector. With each heart pulse the detector signal varies. This variation is converted to electrical pulse. This signal is amplified and triggered through an amplifier which outputs +5V logic level signal. The output signal is indicated by a LED also which blinks on each heart beat.         For a 25-year old, heart beat is about 140-170 beats per minute while for a 60-year old it is typically between 115 and 140 beats per minute.        When a finger is put in the sensor, it displays the beats per minute (BPM) rate.        Fig 2. Heart beat measurement         If the pulse rate is 60 BPM (beats per minute) there will be a pulse every second. The duration of one heart beat is one Heart Beat sensor Temperature sensor (LM 35) ARM processor (LPC 2148) LCD (16X2) GSM modem (SIM 300) International Journal on Recent and Innovation Trends in Computing and Communication                                                            ISSN: 2321-8169 Volume: 2 Issue: 6                                                                                                                                                                                                1429 – 1431 _______________________________________________________________________________________________ 1430 IJRITCC | June 2014, Available @ http://www.ijritcc.org _______________________________________________________________________________________ seconds or 1000 x 1ms. Dividing 60,000 by 1000 will give the correct result of 60. D. LCD:  LCD is a flat electronic visual display. Liquid Crystal Displays (LCD) have materials, which combine the properties of both liquids and crystals. Light modulating properties of liquid crystals are being used for the video display in the LCD. An LCD consists of two glass panels, with the liquid crystal materials sand witched between them LCD are more reliable and energy efficient. Its low power energy consumption makes it to be used in battery powered electronic devices. LCD display is used to display the message after receiving SMS from doctor.  E. GSM MODEM: SIM 300 GSM modem is a wireless modem that works with a GSM wireless network. A GSM modem is a specialized type of modem which accepts a SIM card, and operates over a subscription to a mobile operator, just like a mobile phone. From the mobile operator perspective, a GSM modem looks just like a mobile phone. These GSM modems are most frequently used to provide mobile internet connectivity, many of them can also be used for sending and receiving SMS and MMS messages. We have used SIM300 GSM module. It is an Advanced Low cost modem for wireless GSM communications which includes sending and receiving text messages.          An external GSM modem is connected to ARM board through a serial cable on a UART0.Like a GSM mobile phone, a GSM modem requires a SIM card from a wireless carrier in order to operate.             As mentioned in earlier computers use AT commands to control modems. Both GSM modems and dial-up modems support a common set of standard AT commands.  III. DOCTOR SIDE UNIT   A. ANDROID             Android is a Linux-based operating system for mobile devices such as smart phones and tablet computers. It is developed by the Open Handset Alliance led by Google. Google releases the Android code as open-source, under the Apache License. The Android Open Source Project (AOSP) is tasked with the maintenance and further development of Android. The version used here is Android 2.2 Froyo was released, based on Linux kernel 2.6.32 is used to carry out our project work. Here smart-phone used is the Android 2.3 Micromax’s Ninja. The application software is developed for android using Eclipse software and java programming language. The software decodes each SMS originating mobile number, and the transmitted patient’s temperature and heart beat rate. On click the data is compared with reference level  of temperature and heart beat then back SMS is sent to the patient that his health is OK or NOT. The written android application is responsible for analyzing the data and triggering actions appropriately.    IV. HADWARE & SOFTWARE SPECIFICATIONS  A.

The hardware is successfully implemented for remote health monitoring. The message in Fig 4.shows for the heart beat of 150 BPM and temperature of 37°C.                                                  VI. CONCLUSION         In this project the system allows taking data of patients sending it through SIM 300 to the doctor who moves around with Android operating system in mobile. This system permits great freedom to patient and gives them confidence that medical services can be delivered in time at right spot. It is also easy to use and provides accurate measurements with low cost.
