I have to build an arduino project to control humidity in a closed biosphere. The humidity is measured with a HTD21u humidity sensor. the temperature should be regulated by a Peltierelement.

Do you have a question?
Does there exist already exist a basic program for this?

As a complete workable product?
Maybe, maybe not.
But there'll be projects using those components
Can you supply a link to the HTD21u as I'm having difficulty finding a humidity device with that part number.
The principle would be the same as for a Peltier heating/cooling system but your using a humidity sensor instead of a temperature sensor.
Here is a heating/cooling example that outlines the principle needed of using a PID controller to regulate the temperature using Peltier plates. The main difference for you would be using a humidity sensor instead and maybe no need to cool the plates.
