Iot based health monitoring system

Health monitoring is the major problem in today’s world. Due to lack of proper health monitoring, patient suffer from serious health issues. There are lots of IoT devices now days to monitor the health of patient over internet. Health experts are also taking advantage of these smart devices to keep an eye on their patients. With tons of new healthcare technology start-ups, IoT is rapidly revolutionizing the healthcare industry.

Here in this project, we will make an IoT based Health Monitoring System which records the patient heart beat rate and body temperature and also send an email/SMS alert whenever those readings goes beyond critical values. Pulse rate and body temperature readings are recorded over ThingSpeak and Google sheets so that patient health can be monitored from anywhere in the world over internet. A panic will also be attached so that patient can press it on emergency to send email/sms to their relative

4. Introduction This health monitoring system is composed of two parts, which are portable remote medical monitoring unit and the monitoring center . In this project, we propose a remote medical monitoring system for heart beat rate and temperature data. Monitoring center is a station which consists of real time analysis and a warning mechanism for emergency and diagnosis.

5. DRAWBACKS OF EXISTING SYSTEMS The systems are not portable. The patients or the family members of the patients can’t able to understand the analog signals. Complex system and difficult to operate.

6. MAIN OBJECTIVE The specialist at a distance can monitor the patient condition so that he/she can save the life. This system is to be available at reasonable prices. Embedded technology is to be use for monitoring the patient condition easily. Easy to operate.

9. ATMEGA 328P The  ATmega328  is a single-chip microcontroller created by Atmel in the megaAVR family (later Microchip Technology acquired Atmel in 2016). It has a modified Harvard architecture 8-bit RISC processor core. PIN DIAGRAM

10. SENSORS HEART RATE SENSOR TEMPERATURE SENSOR (LM35) Pulse Sensor is a well-designed plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart rate data into their projects. The sensor clips onto a fingertip or earlobe and plugs right into Arduino. It also includes an open-source monitoring app that graphs your pulse in real time. LM35 is a temperature measuring device having an analog output voltage proportional to the temperature. It provides output voltage in Centigrade (Celsius). It does not require any external calibration circuitry. It is a 3-terminal sensor used to measure surrounding temperature ranging from -55 °C to 150 °C. LM35 gives temperature output which is more precise than thermistor output.

11. GSM SIM MODULE MAX232 A GSM module or a GPRS module is a chip or circuit that will be used to establish communication between a mobile device or a computing machine and a GSM or GPRS system. The modem (modulator-demodulator) is a critical part here. The  MAX232  is an integrated circuit first created in1987 by Maxim Integrated Products that converts signals from a TIA-232 (RS-232) serial port to signals suitable for use in TTL-compatible digital logic circuits. The MAX232 is a dual transmitter / dual receiver that typically is used to convert the RX, TX, CTS, RTS signals.

12. 16*2 LCD DISPLAY POWER SUPPLY An LCD is an electronic display module which uses liquid crystal to produce a visible image. The 16×2 LCD display is a very basic module commonly used in DIYs and circuits. The 16×2 translates o a display 16 characters per line in 2 such lines. In this LCD each character is displayed in a 5×7 pixel matrix. Here we are using a 5V DC power supply. In general, a 5VDC output is obtained from a 50VAC or 240VAC input using a combination of transformers, diodes and transistors.

13. WORKING OF THE SYSTEM There are mainly two parts of the system, one transmitter and the other one is receiver. In the transmitter, We have heart beat sensor and the other temperature sensor. All the sensor are connected to the patient. The microcontroller monitors all the system in the transmitter if any abnormality in the patients condition then it sends the signal so that the receiver will capture the signal and will work according to that.

14. ADVANTAGES Bridging the gap between doctor and the patients. Best to be used on rural areas. Compare with compact sensors it gives better performance. Easy to operate. Low cost. Portable.

15. DISADVANTAGES The system may get hacked because the data security system is not included. If power supply fails then the circuit will not work.

16. APPLICATIONS It can be used in ICUs, operation theatres etc for monitoring the health condition of the patient. It can also be used in old age homes to monitor the various parameters of a sick person. It can be used in daily life to maintain a healthy life style.

17. FUTURE SCOPES Multiple parameters like Blood Pressure, retinal size, age and weight can be included as controlling parameters in the future. The whole health monitoring system , which we have proposed can be integrated into a small compact unit as small as a cell phone. This will helps the patients to easily carry this device with them wherever they go.

18. CONCLUSION Wireless technology is emerging as a significant element of next generation healthcare service. Portable and easy to use. Prevention is better than cure. Modern technologies have developed that promotes comfortable and better life which is disease free.
