Sokaknak volt ebből problémájuk - mármint általánosan, napfény+infra szenzor - külföldi fórumokon, viszont erre van egy egyszerű megoldás :
"Sunlight doesn't change quickly. If your illuminating IR LED is pulsed on/off, e.g. at 25 kHz then you can simply measure the photocurrent at every pulse: add all measurements when the LED is on, subtract all measurements where the LED is off. When you write that down, you'll see that you're simply subtracting the background light, which stays constant."
Gondolom a FaceID is így működik napfényben.
