Immersion detection

A method for determining an immersion of a fluid detection system, comprising:

• providing a fluid detection system comprising a liquid sensor in circuit communication with an air pump and an atmospheric pressure sensor, wherein the liquid sensor, the air pump and the atmospheric pressure sensor are encased within an air and water permeable casing, the casing defining an enclosed air space about the liquid sensor, the air pump and the atmospheric pressure sensor;
• the atmospheric pressure sensor acquiring a first sample value of atmospheric pressure within the casing;
• determining a flood status state of the fluid detection system as flooded or non-flooded;
• in response to a determined flooded state, the atmospheric pressure sensor acquiring a second sample value of atmospheric pressure within the casing;
• comparing the first and second pressure samples;
• and
• determining that the fluid detection system is immersed in a fluid if the second sample value is greater than the first sample value.
