pulse detection circuit
I have used one pulse detection circuit shown in the link(**broken link removed**) using lm 358.it displays my heart rate as led blinking.but each time i have to adjust the sensitivityy and trigger level of the amplifier as light condition changes.Also the same must be done for other individual who places there finger in the module. what may be the problem can any suggest any alternative circuit for my project. i have heard one pulse oximeter ic is directly available is it so from where i can get it plz let me know the details.
