Claim:
A housing for installation of a loop sensor in a receiving medium under a top surface of the receiving medium, wherein the loop sensor includes a wire, the housing comprising: a hollow portion of the housing formed at least in part by separable portions, the separable portions being configured such that in a default position the separable portions contact each other at or near a first end of the housing, wherein the separable portions are further configured to resiliently flex out of the default position to permit the wire of the loop sensor to be installed in the hollow portion, the hollow portion being formed such that, responsive to installation of the housing in the receiving medium, the hollow portion of the housing provides a sensor path for the wire of the loop sensor through the receiving medium, the sensor path having a sensor shape in the plane of the top surface of the receiving medium; one or more protrusions, extending outward from the housing, configured to secure the housing within the receiving medium; and a retaining lip disposed at or near a second end of the housing, the second end of the housing being opposite the first end of the housing, wherein the retaining lip is configured such that responsive to installation of the housing in the receiving medium, the retaining lip engages the top surface of the receiving medium to maintain the wire of the loop sensor in the hollow portion of the housing at a predetermined depth below the top surface in the receiving medium.
