Abstract
This application relates to a moisture ingress sensor. In particular, this application relates to a moisture ingress sensor that can detect liquid ingress into an electronic device. The moisture ingress sensor can include a resistor, an N-channel MOSFET, an operation amplifier, comparators, and an AND logic gate. The moisture ingress sensor is configured to provide a lower power means for accurately detecting moisture in an electronic device. Multiple areas of the electronic device can include the moisture ingress sensor in order to optimize the detection of moisture for at a variety of regions of the electronic device. Additionally, the electronic device can record signals from the moisture ingress sensor and shut down components of the electronic device that could be affected by the detected moisture. Furthermore, the moisture ingress sensor can be tuned to detect one or more types of liquids.
