Abstract
A sensor includes a plurality of detecting units and a sensing unit. Each of the detecting units includes a pair of electrodes and a detecting area formed between the electrodes, and is configured to cause a change in electrical resistance between the electrodes as conductive particles accumulate. The sensing unit outputs a sensing signal if at least two or more of the detecting units experience a change in electrical resistance.
