        One application of the photoelectric sensor is used in bathrooms where we do our business. Instead of using the nasty wicked flushers that everyone uses, engineers came up with a great idea . The bathroom sensor whole shebang analo! gous this, first of it is implant on a rampart and set at a low range readability, belike no more than three feet.
