2.  INTRODUCTION  SCOPE  WHAT IS HEART BEAT,RESPIRATION AND TEMPERATURE?  WHAT IS WIRELESS IS HEART BEAT,RESPIRATION AND TEMPERATURE?  BLOCK DIAGRAM  CIRCUIT DIAGRAM  HARDWARE AND SOFTWARE  ADVANTAGES AND DISADVANTAGES  CONCLUSION

3.  The aim of this project is to monitor the parameters of human body such as heartbeat pulse,temperature and respiration rate through wireless

4.  This project which is used to measure the heartbeat of a human.  This project we are going to measure the heartbeat for some few seconds.  Using pc as well as lcd.

5.  Rf transmitter  Rf receiver  Heartbeat sensor(photo transistor&photo receiver)  Respiratory unit  Thermistor  Signal conditioning unit(SCU)  Micro controller  LCD display  Fsk  Dfsk  pc

6.  Photo transmitter used to transmitt the rays to receiver side.  Between the photo transmitter and receiver human finger is used to measure the pulse of human body.  Transducer is used to convert pulse energy into electrical energy.  Thermistor is use as respiration sensor.  The respiration rate is 15 to 25 for normal person.  A alaram signal give when it extends or going to low level.  When we hale the air there will be a temperature in the nose that may equal to room temperature.

7.  It is constructed with operational amplifier.  Op amp act as comparator used to generate square pulse.  The square shape pulse is given to pulse shaping circuit which pulse is converted to TTL logic pulse in order to accept this signal.

8.  It is constructed with infrared tx and rx.  The probe fixed in the finger to identify the blood flow.  Then the output of the oximeter is given to mc through scu.

9.  Patient database maintained individually so we can avoid the man made error.  Continuous monitoring of the patient is possible.  Reliable.  Economical.  Easy to implement.  Low pwer consumption.

10.  In this project mc may be atmel or pic both are flash type mc in which we have already programmed.  The mc received the signal from the above sensor and compared with actual value.  If it is below or above the abnormal value the mc activates the driver circuit for alarm.  The alarm makes the sound for indication. Also this will control the oxygen pump injection level according to the pulse and respiration of patient.  The output will be given to the mc through any one of its input pin.

11.  Then it transmitted to PC using RF rx by FSK modulation.  FSK is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier wave.  The most common form of frequency shift keying is 2FSK and it is received in PC using RF rx by DFSK modulation.

12.  The datas will be displayed in the PC using RF rx by DFSK modulation and the datas will be displayed in the PC (pulse output will be given to the PC through serial port (com port).  Then the received serial input is converted into parallel data and that will be monitored in the PC as well as in LCD also.
