Thank you for your quick response!
The box isn’t completely enclosed, we’ve added an air exchanger to maintain air circulation with the outside environment. However, the challenge is that the outer environment is salty because we’re near the sea. We need to prevent the salty air from entering the box since it contains sensitive electronic components.
Using a humectant solution might not work for us because we need to adjust the humidity level dynamically over time using a program. The box dimensions are 50cm x 40cm x 100cm, and we’re targeting 50%-60% humidity with a temperature range of 10-15°C.
We’re located in a coastal area in Sri Lanka, so I’d appreciate any advice on how to manage this effectively.
