Abstract: A flood sensor apparatus configured to send a signal to a computing device causing the computing device to turn off a utility at a site experiencing a flood. The flood sensor apparatus may include a housing and a back cover which, when coupled together, form gaps along a perimeter of the flood sensor apparatus such that fluid (e.g., water) may quickly fill and drain an interior of the housing. These gaps may be large enough such that the fluid may quickly fill and drain the interior of the housing but small enough that debris may not clog the gap or enter the interior of the housing. The back cover may include a rib extending from an inner face of the back cover and that that runs along a perimeter of the inner face. The rib may prevent tampering of a flood sensor located in the interior of the housing by blocking any object that may be inserted into the gaps.
