Automatic Rain Gauge

A rain gauge is a instrument that measures how much rainfall falls in a given set time.

The Ancient Greeks were the first people to monitor rainfall at around 500 b.c. They were followed by the Country of India, around 100 years later, using bowls to collect the water. Measuring the rainfall give the Greeks and Indians an idea to collect the data, and then tax there citizens, according to how much growth of pastures from the rainfall.

According to history, the first known rain gauge was made by a man called Cheugugi from Korea, but we also find other sources that credit Jang Yeong Sil to be the first person to develop a rain gauge, by refining an existing gauge.

In the United Kingdom Christopher Wren developed the first rain gauge, called the tipping bucket in 1662 A.D.

Usually when measuring how much rain has fallen, the measurements are taken in millimetres, but sometimes it can be measured in inches or centimetres. They can either be read by a person, or a automatic weather station. The amount of time between readings depends on the agency that requires the reading.
