Fingerprint Module with extra cover layer

Post by mbn12 »

Hello guys,

I would like to build a project using the fingerprint sensor from Adafruit ( ID 751 ) and mount it behind a thin layer of glass.

Could someone who has this module and a spare piece of acrylic or glass (1 - 3 mm) please test if this work?

The extra layer, being fully transparent, shouldn't affect the lightning. But I don't know if there's something about image focus, regarding what the sensor was calibrated, or something like that.

Thank you,

Mario

No, this won't work. The the finger must be in direct contact with the glass.

Too bad... :/

Thanks for the reply.

If someone knows a module that allows this, please post here. This would enable some pretty nice case designs.

Thanks
