Abstract
An apparatus comprising: a body having an aperture dimensioned to receive an air-borne particle of corresponding size; first and second electrodes positioned within the aperture between which a potential difference can be applied; and a measurement circuit configured to measure an electrical property between the first and second electrodes such that the presence of the air-borne particle within the aperture can be detected based on a change in the electrical property when the air-borne particle contacts both the first and second electrodes.
