Humidity Meter

     This meter will measure the environment's humidity, between 0 and 100%. The component level chip used was the HTM1505, whose signal is buffered and filtered to give an analog reading, with resolution to .162%. The casing is covered on top, for protection from the environment, but mesh on all sides, to allow the site's humidity and the meter's internal humidity to balance. This allows for maximum accuracy, but still provides the circuitry protection from harsh environmental conditions.
