iPhone Dynamic Island Notch Sensors

Did you know that little "notch" in your iPhone (or a "dynamic island" on newer phones) is actually a bank of 8 different sensors and devices?

It seems like an annoying little notch in your phone screen, but in reality is houses:

• Infrared camera for FaceID

• Flood illuminator for FaceID to work in the dark.

• Proximity sensor to see how far away the phone is from objects

• Ambient light sensor to know how bright to set the screen

• Speaker for phone calls and audio

• Microphone (one of many on the phone)

• Front camera for selfies

• Dot projector for FaceID to project 1,000's of little dots and collect the info to map your face.

It's actually quite astonishing how much tech there is in this 1 inch space.
