1. A portable, resistive, water sensing apparatus comprising a housing, a circuit for detecting changes in resistance within the housing, an alarm connected to and driven by the circuit, and an elongate sensor, one end of which is secured to the housing and is connected to the circuit, and the other end of which has two exposed contacts, so that the circuit can detect changes in resistance between the exposed contacts to detect the presence of water, which sensor has a rigidity which is sufficient to enable it to maintain a configuration in which it supports the whole weight of the sensor to enable the apparatus to be hung by the sensor and has a flexibility which is sufficient to enable it to be bent manually to a desired configuration.
