Historical information

A battery operated device that is rectangular in shape with a sensor plate on top and an on/off switch on one end. At the other end is a round lid that screws off to allow a round 9 volt battery to be inserted. It was designed so that when placed outdoors would emit a noise at the first drop of rain, enabling vision impaired people to retrieve their washing from the line.
