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.
Claims8
A sensor comprising:
- a plurality of detecting units each including a pair of electrodes and a detecting area provided between the electrodes, the detecting area being configured to cause a change in electrical resistance between the electrodes as conductive particles accumulate between the electrodes;
- and
- a sensing unit for outputting a sensing signal if at least two or more of the detecting units experience a change in electrical resistance.
