The project is totally based on microcontroller.It uses PIC16F874/77 microcontroller which is based on microchip’s Mid-Rangecore.It uses an IR sensor (The sensor consists of an IR light emitting diode transmitter and an IR photo detector acting as the receiver) which will detect the volume of blood per second passes through the finger. Using this project we can easily find the heartbeat of a person per second without a doctor. The microcontroller check the status of IR sensor and based upon it will send a signal tothe LCD display. This circuit is being tested in protous and in breadboard and is properly working. This project is basically made for use in hospitals and can be used for simple experiments in colleges and schools. It is a cost effecting project, easy to use, reliable and simple.
