DIY Pulsoximeter developed with two Arduino

Pulse oximetry is a non-invasive method for monitoring if a patient’s oxygenation is unstable and Arduino user die_Diode sent us his version of a DIY Pulsoximter developed with two Arduino: Arduino Mega for the oximetry electronics and Arduino Uno for the graph. The electronics includes LED Driver, Photo current transformation, patient-dependent calibration LED, Active filters, Nellcor SpO2 sensor. Adafruit […]
