A single sensor may not be able to accurately detect people flow. You can try a sensor array. I think it should be possible. It depends on your actual environment and installation location.

JimmyKudo posted on 2018-10-31 21:51 Mr. Xia, do you have any good ideas or materials for counting people flow at the entrance based on L1 ranging?
A single sensor may not be able to meet the requirements of accurate people flow detection. You can try sensor arrays. I think it should be possible to achieve it. The specific details depend on your actual environment and installation location.
