Humidifier and digital hygrometer/thermometer

A humidifier and digital hygrometer/thermometer device for use with a stringed, musical instrument having a box with a characteristic depth and a sound hole with a characteristic diameter and parallel, spaced-apart strings that pass above said sound hole and wherein said device configured to maintain the humidity within said box to a specifiable level when said musical instrument is not in use and monitor the ranges of temperatures and relative humidity experienced by the device when said device is in use, said device comprising:

• a sponge,
• a container having an interior space and an enclosing sidewall with opposing parallel sides that are separated by a distance that defines the width of said container, and a right and a left edge portion that connect to said opposing parallel sides and wherein the
• distance between said edge portions defines the length of said container, and proximal and distal ends and a centerline that connects said ends and wherein the distance measured along said centerline between said ends defines the height of said container, and an opening into said container at the proximal end of said container, and wherein the interior space of said container is configured to accommodate said sponge
• a case having an interior volume and a top surface and a bottom surface, wherein said case is affixed to said container
• a first means for measuring the relative humidity in the environment surrounding said first means at an instant in time and providing a first electrical output signal, and wherein said first means configured to fit within said case interior volume,
• a second means for measuring the temperature in the environment surrounding said second means at an instant in time and providing a second electrical output signal, and wherein said second means configured to fit within said case interior volume,
• a digital display means affixed to said case top surface,
• a processing element configured to receive said first electrical output signal and cause said digital display means to digitally display said relative humidity measured by said first means, and to receive said second electrical output signal and cause said digital display means to digitally display said temperature measured by said second means, and wherein said processing element configured to fit within said case interior volume, and
• wherein said width, length and height of said container are chosen so as to enable said container, when in use, to fit between said parallel, spaced-apart instrument strings and to pass through said instrument sound hole so that said distal end of said container is situated in said instrument box when said bottom surface of said case rests against said parallel, spaced-apart instrument strings.
