This project is developed for the Doctors to test the heart beat of the patient and if anything strange, to inform the doctor through GSM and also stores the status in a server through RF.
The main part of the Unit is Microcontroller, Heart beat sensor and GSM. The heart beat sensor is connected with the body. If the value is below or above a certain range, it sends signal to the Microcontroller unit.
The micro controller immediately sends signal to the server through RF transmitter and also sends signal to the GSM controlling circuit. The GSM unit sends to a SMS to the Doctor.
The RF receiver receives the signal and accordingly displays the status of the heart beat. If the doctor is not available at the particular time, the details are stored in the PC and he can analyze it when ever necessary.
The microcontroller program is written in assembly language and the port programs are written in Visual Basic. The microcontroller used is PIC 16F73
