Blocking or shielding?

    Hi!
    I'm setting up an artwork using the X2M200 and want to hide the sensor away from sight.
    Are there any materials that blocks the signal and others that don't?
    If there is can these be used to shield from interference?

    I've done some testing on my own, like the sensor dosen't seem to work through a PC monitor.

    Hope someone can shine som light on this for me :)

    Hi Olle!

    We have written an app note about different building materials we can penetrate, see: https://www.xethru.com/community/resources/signal-attenuation-from-building-panels.65/

    For hiding your sensor, it is important that the material has low dielectric constant, see this site: http://www.rfcafe.com/references/electrical/dielectric-constants-strengths.htm We use nylon in our 3D printed casings.

    Metal is a good reflector and will efficiently shield the signal, you can experiment with e.g. aluminum foil.

    Great if you can share your artwork when you're ready!
