Measuring rain levels for agricultural purposes, the rain gauge was first created in 1441 by the son of King Sejong, whose dynasty ruled over the Korean people. The King sent a rain gauge to every village and they were used as an official tool to measure the farmers potential harvest. Sejong also used these measurements to determine what the farmers land taxes would be. This creation was 200yrs before inventor Chris Wren created a rain gauge (tipping bucket rain gauge c.a.1662) in Europe.
