Triggering touch sensor with an object

Postby Orf Quarenghi » Wed Oct 23, 2019 5:14 am

Hi.
Is there a way to trigger a capacitive touch sensor (1129_1B) using an object instead of a finger/hand?
I need to use something very slim so that I'll be able to hide it between two cardboard sheets.
Thank you

Most metal objects will be able to trigger it. For example, even a small wire (30AWG) will typically trigger the sensor.

Thank you.
I am trying with tinfoil and it works.
Alas, I will not be able to use this solution.
I'm building an interactive book with big white pages onto which I will project video clips.
The problem is that the tinfoil may rest against the sensor much more than 45-60 seconds, so the periodic sensor's recalibration this time is working against me... I'll switch back to RFID for this project...
