Fluid detection systems and methods using the same

A method of fluid detection, comprising, with a fluid detection system comprising a sensor module and an electronics module, the sensor module comprising a sensor housing, a liquid flow path extending through the sensor housing, and a sensor element disposed at least partially around a perimeter of the liquid flow path, the electronics module comprising a controller communicatively coupled to the sensor element:

• detecting, with the sensor element, a capacitance within the liquid flow path;
• conveying a sensor signal indicative of the capacitance to the controller;
• determining a detected capacitance within the liquid flow path with the controller;
• comparing, with the controller, the detected capacitance to a capacitance threshold;
• and
• determining, with the controller, whether a wet event has occurred in the liquid flow path based at least in part on said comparing the detected capacitance to the capacitance threshold.
