[IDEA]A rather interesting LD2450 application from the official HLK video that also applies to the 2A.

We found this one video from HLK promoting the use of the LD2450, where a woman, near a fan, and the LD2450 adjusts the size of the wind speed depending on the distance between the two.

One of the other things that the LD2450 utilizes is the ability to track X and Y coordinates so that the fan can track the user's angle and blow in the direction of the user.

It's a pretty strange application, combining speed and distance.
