Hi,
I'm working on my thesis and I need to calibrate some gas sensors that I'm building.
I need controlled conditions(temp, RH and a known gas concentration) in order to calibrate the sensors.
I'd love to know some idea to make a sealed box in which I trace and vary those parameter.
I've been thinking about buying tailor-made cristals and trying to find some kind of plastic/resin to fill the gap between them. To control temperature and humidity I could use a temperature and humidity sensor. I could use some kind of valve to introduce the neccesary amount of air inside the box. Anyway, this is just a quick approach and it may not even work.
Do you have any idea about how to make it? At least how to make a small part of it(For example how to vary humidity)?
Cheers
