Hello everybody. Today I show a device that took me a lot of time in development, and can come useful to detect water condensation, you know, the one that makes your tools rusty, or your house mouldy. It was even used in a research this last spring, aimed to assess the effectiveness of face masks. Because this sensor is even capable of detecting the tiny droplets that come with our breath, so it was used to make a quantitative comparation between different filter technologies.
More details in the description of the video.
Hope you'll find it interesting.
