Abstract
A pest sensor and a detector for use in a pest sensing system are described. The pest sensor comprises a processor configured to: receive a first signal indicative of a first impedance across a first sensing circuit; receive a second signal indicative of a second impedance across a second sensing circuit; and in response to detecting that one of the first or second signals differs from the other by more than a predefined difference threshold, output an indication of pest activity.

A pest sensor comprising a processor configured to:
- receive a first signal indicative of a first impedance across a first sensing circuit;
- receive a second signal indicative of a second impedance across a second sensing circuit;
- and
- in response to detecting that one of the first or second signals differs from the other by more than a predefined difference threshold, output an indication of pest activity.
A detector for use in a pest sensing system, the detector comprising first and second sensing circuits, each comprising:
- a first electrode connected to a first track running along a longitudinal direction;
- a second electrode connected to a second track running substantially parallel to the first track;
- and
- sensing tracks in the form of a set of fingers located between the first and second tracks, a first set of the fingers being connected to the first track only and reaching towards the second track, and a second set of the fingers being connected to the second track only and reaching towards the first track, the first and second sets of fingers being interdigitated with each other and separated from each other such that pest activity can be detected via a reduction in the impedance between the two sets of interdigitated fingers, measured via the first and second electrodes.
