Human Body Monitoring System Using Wsn With Gsm Andgps

The main aim of our paper is to monitor and analyze the human body temperature, blood pressure (BP), Pulse Rate and ECG and tracking the patient location. The human body temperature, BP, Pulse Rate and ECG are detected and can be sensed by using respective sensors. The sensed information is send to the PIC18F4520 microcontroller through signal conditioning circuit in the patient unit. A desired amount of sensor value is set and if it is exceeded preliminary steps should be taken by the indicating by buzzer. The sensor information will be transmitted from the patient unit to the main controller unit with the help of GSM communication system which is connected with the microcontrollers in the both units. The main controller unit will send those sensed data as well as the location of that patient with the help of GPS Module to the observer [1]. The observer can receive the SMS sent by GSM module and further decision can be taken. The message is sent to a mobile phone using Global system mobile (GSM) Modem.
