Since I had lots of interrupt-trigger problems, I analysed the output of the RE2008 and like you see, I have lots of noise. Between output and GND is a 100k resistor and the power supply is a ams1117 linear regulator. Do you have any idea, how I can get rid of the noise?

It will tell you how to ask a question and what information you need to supply.
In your case it is a schematic, hand drawn is fine Fritzing is not.

Well it is the most basic circuit
Well I actually meant the full schematic, because there are ways of reducing noise and without a schematic I don't know what you have tried and what you haven't.
For example:-
So my first question here is what values of capacitor do you have on the input and output terminals?
I powered the given schematic by the pictured esp8266. Once with 5V from the USB Power supply and once from the 3.3V pin of the esp. and there we basically have our ams1117. The result was similar or same.
I ask for a schematic and yet you answer with words.
If that is your final word on the matter this is my final word also.
I agree! I think many that do not understand basic electronics well enough to understand a schematic is the basic language spoken by electronic engineers and techs. Without that and not having the unit if front of us it is all but a hopeless cause.
