Comment on Touch sensor part ID?
Sadbutdru@sopuli.xyz 5 days agoI have the datasheet for the qt113, it indeed uses 2.5-5 V. But I don’t know what wide is going on there.
Is that other black component a transistor, and that’s what’s doing the switching for the lights based on the sensor output? Or is this whole board sending a digital signal to something else that switches the lights?

It’s way out of my knowledge but it looks like the electrode for the touch is missing. It should be on the left corner where the “02” is printed on.
As you guessed the black thing is a transistor and should switch a led or probably a 5V relay. But please be careful since I’m guessing too xD
