Title: HTTM Capacitive touch switch button module
Post by: thehardwareman on May 26, 2020, 09:03 pm
I bought a few HTTM Capacitive touch switch button module (https://heltec.diytrade.com/sdp/2044581/4/pd-6785993/19510183-2583775/HTTM_Capacitive_touch_switch_button_module.html), just because they looked cool :)

Got them today and connected +5V and GND to one. Then I measured the output voltage. I thought this would give either 0 og ~5V out, but no. It give 3.9 or 4.7 v out.

I search the big internet to find any good solution on how to "convert" the output to logic 1 or 0, but have not found anything. Perhaps some gurus in here have any suggestions?
