What are depth sensors?

Depth sensors are tools that tell how far away something is from them, just like when you measure how tall your toy is with a ruler.

Imagine you have a depth sensor like a special kind of eye. It looks at things and tells you how close or far they are, without touching them. This helps robots, phones, and even video games know where you are or what’s around you.

Like a Tape Measure That Doesn’t Touch

Think about measuring the distance between your nose and a wall, usually you’d use a tape measure. A depth sensor works like that, but it doesn’t need to touch anything. It sends out signals (like tiny invisible waves) and sees how long they take to come back, just like when you shout in a cave and listen for the echo.

When You Play with Friends

It’s also like playing hide-and-seek, if you can tell how far away your friend is just by looking or listening, that’s what a depth sensor does. It helps machines "see" how close things are, making them smarter and more helpful!
