Pulse Oximeter using PSoC
Abstract: A pulse oximeter to measure the oxygen saturation in blood as well as heart rate was developed using PSoC. The method proposed here is to transmit light of two different wavelengths through the finger and tissues and to measure the change in absorption intensities. The signals are obtained as photoplethysmograph (PPG) waveforms. The pulse oximeter finds the variations in both the waveforms and calculates the SpO2 and heart rate of …
