1. A liquid detector comprising:
a housing adapted to couple to a surface of an external reservoir having side walls and a bottom surface, wherein the bottom surface has a profile including first and second portions that are lower than the side walls, and at least a lowest point of the second portion is lower than at least a point of the first portion; and
a sensor mounted within the housing and having a sensing surface configured to detect a liquid on an outer surface of a first of the side walls,
wherein the first of the side walls includes an inner surface having a normal axis extending in a first direction,
the sensor is mounted such that the sensing surface is in a substantially vertical orientation and the sensing surface is spaced a first distance from the first of the side walls in the first direction,
the sensing surface intersects the normal axis, and
the lowest point of the second portion is spaced from the first of the side walls by a second distance in the first direction, and the second distance is greater than the first distance.
