IR LED and Photodiode. Note: Proper alignment of infrared LEDs and Photodiode is necessary. After orienting the IR LEDs to the photodiode, adjust VR1 till Red LED turns on and buzzer stops beeping.

By designing out the photodiode’s high non-linearity, which impairs the operation of SpO 2 measurement circuits, ams OSRAM is enabling wearable device manufacturers to differentiate their ...
