Windows can use the sensor for “adaptive brightness,” automatically increasing your display brightness when you’re in a bright area, and decreasing the brightness when you’re in a dark room.

The options here let you control whether adaptive brightness is used when you’re on battery or when you’re plugged in. For example, you could disable it when you’re plugged in and leave it enabled when you’re on battery power.
