The primary function of this system is to monitor the Heart Beat of the Patient and the Data collected by the sensors are sent to the Microcontroller. The Microcontroller transmits the data on LCD. It works on the principle of light modulation by blood flow through finger at each pulse
Description in detail:
The functioning of Heart Beat device is based on the truth that the blood circulates for every heartbeat that can be sensed by using a circuit formed by the combination of aIR LEDand Transistor. Depending upon the rate of circulation of blood the heartbeat rate per minute is calculated.
- This project can be used in the home for patients or ill person or old person.
- The same project can be used in hospitals.
It mainly consists of following blocks:
- Microcontroller based control unit with regulated power supply.
- Heart Beat Sensor.
- LCD Display.
- Buzzer that beeps for critical conditions
