Did you know that sculk sensors already exist in 1.17? You might think I'm crazy because they aren't even in the creative menu.
But using the /give command, you can obtain a fully-functional sculk sensor in 1.17, it just doesn't have a creative inventory entry just yet, nor a way to obtain it in survival without commands.

Happy Crafting!
