Use P-NUCLEO-53L1A1 to be fall-detection and put on wall, possible?

Description:

We currently use P-NUCLEO-53L1A1 (3 sesnors) to be a fallen-detection sensor product.

Instead of putting this interior of ceiling (coz sometimes it has height problem for installing),

we plan to put it into wall with 4 sensors (each sensor has 27degree view, so if we put 4 sensors onto wall)

and is it possible to check ranging distance via horizontal view instead of vertical? Any experience sharing.. thx

Motive:

Take 4 ranging sensors onto wall instead of setting up them onto ceiling, any difference or feasibility

problem for this idea?

    Surely, the whole point of an Evaluation tool like the 

    P-NUCLEO-53L1A1 is to let you try it out - in other words, to Evaluate whether it works?

    The clue is in the name!

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Hi Andrew,

    Not clear about ur explanation, 

    as my checking situation, we use it as a ranging sensor device set-up at top of ceiling so any object is moving around

    below device or fall-down or even jumping can be scanned and distance difference found by a vertical view.

    However, if we put sensor device at higher wall instead of ceiling, when object or person is trying to moving or falling down,

    is a horizontal view of sensors can easily find it same as a set-up at ceiling???

    Andrew's point is that you get to evaluate YOUR use case. You're going to need to point the sensors at the things/distances you want to measure for them to be effective.

    You'd be better off posting to the right forum, or discussing with the engineers supporting your account.
