Libraries and sketch examples in Arduino IDE 1.8.13 for sleep() and wakeup()

[RvanderSpank]

I am not a software developer, so please be kind.

I was trying to make the SDS sensor go to sleep. There is only 1 example in the Arduino IDE (still using 1.8.13), namely "SDS011_example.ino", so no example with sleep() or wakeup(). In the serial monitor it was just listing the values p25 and p10 quickly.
Then I tried to install library version 0.05 from here in the Arduino IDE, after which I got another result from the (only 1) example. Now it lists the values p25 and p10 slowly, so it must contain sleep() and wakeup(), I guess.

My libraries-folder now contains 2 folders, namely "SDS011-0.0.5" and "SDS011_sensor_Library". I tried to compare the content, but they seem exactly the same.. Really strange to me as the result is different.? I even don't know how the Arduino IDE knows which one he has to use..

What I am trying to do is getting the ESP8266 + RTC-sensor + SDS011 + BME280 to work, so for the RTC-sensor to have any use I should need an example with sleep() and wakeup() that works on the ESP8266. Where can I find this (second?) example? Both of my library-folders contain only one (and the same) example. In the end I also want the sensor to sleep during the night.

Thank you very much for all of your effort!
