Temperature and Humidity Control

Hello, I need to design a humidity and temperature control for a little glass camera. At this moment, I have the sensors working(relative humidity and temperature). I will implement the control system with a microcontroller.

The volumen is about 4 liters.

The sensor of humidity is relative to the ambient humidity and goes from 0% to 100%.

The temperature control I think to do with a resistance but the humidity i doesn’t have any idea.

The sensors it is already working.

Anybody can help me with the control system? The temperature range i need is 0 to 100ºC and I need to control the relative humidity of the chamber.

Any idea how can I implement this? Thanks, goodbye.

Your sensors only tell you the current conditions. How are you planning on heating/cooling this space? How are you planning on adding/removing humidity?

For the temperature I thinked in a resistor heat, but, for the humidity I dont have any idea. Sorry for my bad english, i am not english speaker.
