Hey there!,

I am considering using the skywriter gesture sensor for a project I am working on, you mention that it can be mounted behind a non-conductive material (such as fabric or acrylic) Would the sensor work through glass? (around a CM thick)

Cheers,  
Alexon

Tentatively I’d say yes- there’s no reason why it shouldn’t, but I’d need to actually test it to be confident. I’m not sure where I’ll come across 1cm thick glass ( is this a project for mounting behind a shop window or something like that? ) but it can’t be that difficult!

It’s to be mounted behind a two way mirror (so the glass potentially is half silvered, perhaps this might count as conductive and cause issues?)

Thanks for the prompt reply!
