A dynamically self-adjusting sensor is disclosed. In one embodiment, a sample module repeatedly generates an electronic signal related to a characteristic of an environment. A window module receives the electronic signal and provides an average signal for a pre-defined number of the electronic signals. A delta comparator module receives the electronic signal from the sample module and compares the electronic signal with a previously received electronic signal from the sample module to establish a change, wherein an output is generated if the change is greater than or equal to a threshold, the delta comparator module further receives the average signal from the window module and compares the average signal with a previously received average signal from the window module to establish an average change, wherein the output is generated if the change is greater than or equal to a threshold.
