An in-ground sensor having an exterior porous filter, a porous inner screen finer than the outer filter designed to further filter solid particles from the inner portion of the device, a float assembly with a sliding member moving upward in response to buoyant forces for activating a control device which sends a signal indicating the level of moisture within the device proportional to the level of the float. The components are preferably made of a material which is temperature and corrosion-resistant in an environment which may be constantly or repeatedly exposed to moisture and temperature variation.
