Optical sensor simulation

Hello, Your circuit is a simple photoplethysmography device which detecets heart rate indirectly by measuring changes in blood volume. It has a Tx photo diode and an Rx photo diode. The Tx light goes through the tissue and its changes is detected by Rx diode which could measure the heart rate indirectly. I am a professional Electrical / Biomedical Engineer with several years of experience in cardiovascular systems. I can provide you with a full report of this circuit. My price and timing are approximate and will depend on the actual amount of work. Thanks.

Hello I would like to help you with your project. The sensor you use in the project; is the heart rate sensor worn on the finger, right? If you want to explain the operation of your circuit, I can also share with you a video of how signals are generated on a real oscilloscope.
