Microcontroller › 8051 › heart beat sensor counter
hello friends
i wnt to design aheart beat counter circuit ,i should choose the ir method but i cant understand how to count the heartbeat any one please help me.
Hi Balaji,
Are you designing the sensor yourself. If yes post the details with the circuit diagram. Otherwise just post the part number, we can help you.
Sir,
I m trying to work on similar project where i need to measure heart beat of the patient using either IR or LDR methods
i tried alot using 2-3 stages of amplification and low pass filters still was not able to suceed in this project
i m attaching a circuit diagram wysiwyg_imageupload:7979:
I’m sure this project is long gone, but I noticed the schematic provided was using an LDR. That has neither the frequency response nor the sensitivity that would be suitable for this project. You would need a photo diode or transistor for a sensor…
