Moisture ingress sensors

A moisture ingress sensor for minimizing damage to an electronic component of a device, comprising:

• a moisture interface element having an electrical resistance that is adjusted upon exposure of the moisture interface element to a first moisture event such that:
• (i) when a result of a detection of the first moisture event exceeds a threshold, then issuing a first activation signal, otherwise (ii) when the result of the detection of the first moisture event is less than the threshold:
• adjusting the electrical resistance upon the exposure of the moisture interface element to a second moisture event, and issuing a second activation signal upon determining that the second moisture event exceeds the threshold;
• a bias switch that is configured to open in response to receiving any of the first or second activation signals from the moisture interface element;
• a logical component coupled to the moisture interface element;
• and
• a signal processing portion connected to the moisture interface element, wherein the signal processing portion is capable of (i) receiving any of the first or second activation signals, and (ii) sending a corresponding reference signal to the logical component, thereby causing the logical component to utilize the corresponding reference signal to provide a moisture indication signal.

A method for detecting multiple moisture events by a moisture ingress sensor of a computing device, the moisture ingress sensor including a moisture interface element capable of providing an electrical parameter value associated with a detection of a moisture event, the method comprising:

• when the moisture interface element detects a first moisture event:
• providing a first electrical parameter value having a first peak value that is less than a threshold value such that the moisture interface element is prevented from issuing an activation signal to a logic component of the moisture ingress sensor;
• when the moisture interface element detects a second moisture event subsequent to the first moisture event, the second moisture event causes the moisture interface element to provide a second electrical parameter value having a second peak value that includes at least the first peak value:
• providing the activation signal to the logic component when the second peak value satisfies the threshold value,
• causing the logic component to send a moisture indication signal, and
• sending a switch signal to a bias switch that opens the bias switch of the moisture ingress sensor.
