As an electrical Engineering Technology major, specializing in control systems, I know what you need, and can give you multiple options, depending on your own engineering expertise.
Fist, you can purchase ready made , plug and play units such as this -
They include the sensors, with outputs to control heating/cooling, and humidifying/dehumidifying. The unit shown says that it is ideal for sausage making. I would think it would be good for much more, such as making cheese, or aging meat.
The other option is to purchase humidity and temperature sensors, and run the outputs to appropriate inputs to a computer, and write a program to monitor the environment in real time, comparing against desired and programmed parameters, and then using the program to activate heating/cooling, and humidifier/dehumidifier units.
You would also need to build a container unit that can be isolated from the elements in such a way so that you can control the the conditions of that chamber.
Either way, this is a doable project. Good luck, and I hope you are able to build what you need.
