Webcam module sensor [ camera mic switches ]

As I look at the webcam module, I see the left and right mikes, the camera and mike switches, the camera is on led, the camera sensor itself between the switches and one other sensor to the left of the mike switch that I cannot identify. Does anyone know what this sensor is for? Asking for a friend :grinning_face_with_smiling_eyes:

Ambient light sensor.

Just thought I’d anote an image.
