Thank you for the information. I am not able to collect the devices every day and they have to stay outside for two weeks or longer. Because of that, it is important the vent do not let the water comes inside during rain. Maybe it stays dry in combination with silica gel in the case.

Is the Mylar film you have used waterproof or at least hydrophobic?

Hello, the link to the website including the deployment protocol does not work. I am very interested how you determined the sensitivity and what kind of cases you have used. Could you write the actual link into the Support Forum again if possible, please? Thank you very much.
