Abstract
A pest detection device including a capacitive sensor having a plurality of traces that can be capacitively sensed using self-capacitance or mutual capacitance measurements. The sensor including conductive shield traces to facilitate a number of sensing applications. The sensor including a coated portion to facilitate crawling of pests over the sensing area of the circuit board.
Claims20
A pest detection device, comprising:
- a capacitive sensor comprising a plurality of traces disposed on an insulative circuit board and arranged in a sensing area, wherein at least one trace is of a different size than at least one other trace;
- a controller electrically connected to the plurality of traces, the controller configured to sense changes in capacitance of at least one trace of the plurality of traces;
- and
- a power supply connected to the controller,
- wherein the plurality of traces comprises three or more traces.
