Hello I'm developing a photoplethysmograph(PPG). It is very similar to pulse oximeter, but use only the infra red led. I would buy a finger clip probe that i can use in my project. At this moment i'm using a simple IR led and phototransistor for acquire my photoplethysmograph signal but i have very problems. This problems are mainly the finger p

Hello everyone, I'm working on a project that includes a pulse oximeter & blood pressure monitor.. And I'm a bit lost with the coding. We physically made the sensor but not sure whereon the board (what pin) we plug it into. Any help would be greatly appreciated.
Hey all. I need to build a pulse oximeter for my final project in college but i still have one doubt about the wavelengths do these waves need necessarily to be 660nm for the red led and 910nm for the IR led? I have a 875nm wavelength IR led here. Will it be ok? Thanks for the help Aw. And what about the photodiode? Or should I use a phototr

I designed a pulse oximeter and it's working fine with LM 358 as the aplifier. But the output I get is only 3.68v. I tied this to an LED through a resistor so I can visually see the heart beats. But I can't read this output from PIC 16f877. So I used another LM 358 as a basic comparator and tried to get a 5V pulse. But still the output I (...)

Hello, I am designing a PIC18F pulse oximeter. In theory, a very simple design, that uses a photodiode to measure RED and IR light, and gets amplified into a ADC into the PIC. Im using MPLAB as an IDE and need some c language code or a software flow chart to point me in the right direction. Any help would be greatly appreciated. Thanks

What is the 5V for? There are no devices that can convert 19mV to 5V to provide a power supply, even at low currents, even if it could be done, the current consumption at 19mV could be more than 50 Amps for some PICs! Is it for driving the ADC so you can measure the voltage? If it is, please tell us where the 19mV is
