In recent days wireless patient Heart Beat monitoring system Project are gaining high reputation in medical field in terms of providing a reliable and accurate diagnosis for the patient. Here in this project Report “Heart beat monitoring by GSM technology” we implemented a micro controller based heart beat monitoring system based on GSM module.
These systems can easily sense the abnormal conditions of the patient located at remote places by means of a GSM modem. In order to perform these operations we need heart beat sensor, GSM modem, P89V51RD2 micro controller for controlling the auxiliary elements of the circuit.
Microcontroller and GSM Technology
Embedded systems are abbreviated as the computing systems embedded on a single integrated chip. These are special purpose computing systems design to implement specific tasks based on real time constraints.

Heart beat sensor:
The senor concentrate on the flow of blood in the finger the LED emits light with specific intensity on one side on the other side the change in light is measured by the light dependent resistor and detects the heart rate based up on the amount of change in blood in the finger.
