Photodiode heartbeat monitor

PHYS 3330, Spring 2025 · team project

An IR LED and photodiode sensor with an LF356 transimpedance amplifier, AC isolation and a low-pass filter, feeding an Arduino that computed beats per minute every 10 s, in a 3D-printed housing. I helped isolate the noise to find the pulse signal. On demo day it did not detect a heartbeat, a good lesson in how hard low-level signals are to pull out of noise.
