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.
Claims24
A pest detection device, comprising:
- a sensing surface comprising a plurality of traces at least in part beneath a textured material, the textured material having sufficient texture to enable climbing pests to climb across the sensing surface mounted at a nonhorizontal angle of greater than about 30 degrees;
- a controller connected to at least some of the plurality of traces of the sensing surface;
- and
- a power supply connected to the controller.

A method for making a sensor, comprising:
- mounting a circuit board at a nonhorizontal angle, the circuit board including a plurality of traces wherein at least a portion of the traces are coated with a textured material that pests can more easily climb at the nonhorizontal angle of greater than about 30 degrees;
- connecting a controller to at least two traces of the plurality of traces, the controller configured to sense capacitance of at least some of the plurality of traces;
- and
- connecting a power supply to at least the controller.
