Rancangan Pulse Oksimetri Untuk Mengukur Saturasi Oksigen Dalam Darah (SpO2) …

ABSTRACT The design of pulse oximetry to measure blood oxygen saturation (SpO2) based on Arduino UNO was successfully performed. SpO2 measurements by the device are performed by acquiring photoplethysmography signals at the fingertips using a DS-100A probe consisting of infrared led (960 nm) and red (640 nm) and photodiode. The signal from the probe is amplified and filtered with a polar freq…
