NEED OF BLUETOOTH STETHOSCOPE :

1. Our project helps in recording and hearing the heart rate of the patient without the noise arised by the subject’s dress or some other air obstruction.
2. And the recording also helps for the physicians to hear the recordings of the subject if necessary.

1. Its also very beneficial during the pandemic period as it reduces the contact of the patient and the doctor and increases the proximity between the doctor and the patient.
2. Interchangeable chest pieces avoid infection and maintain hygiene
3. It has increased auscultation volume and sound quality than traditional stethoscope

WORKING:

       Our working is very simple where the heart rate of the subject is been converted into electrical signals. These sound waves of the patient is being recorded through the microphone and this microphone helps the sound waves which enter into the control board. These sound waves are amplified using amplifier. Those amplified signal is sent to the controller. The controller has the code where we can determine the electrical signal’s heart rate. Arduino uno sends the signal to the Bluetooth where it can be controlled by any android or ios device where the output can be seen in the respected device. 

In traditional stethoscope, the noise can be arised due to the patients dress or any other obstruction which is rectified using the amplifier in our project where the noise and the artifact can be removed and rectified for the clear heart rate. 

BENEFITS TO THE SOCIETY:

1. Has the recorded signals which can be analyzed by the physicians
2. Increases the proximity of the patient and the doctor(during pandemic)
3. Easy to handle
4. Can be used from long distance too
5. Beneficial during covid pandemic
