Abstract
A porous medium sensor apparatus includes a sensing portion at least partially insertable in the porous medium. The sensing portion has a housing with a gas exchange aperture defined therein and a water-repellant membrane mounted in the gas exchange aperture, the water-repellant membrane preventing water communication through the gas exchange aperture. The sensing portion also has a parameter sensor mounted in the housing for measuring a parameter of the porous medium in which the sensing portion is inserted.
