Design and implementation of tipping-bucket rain gauge

This paper describes the design and implementation of rain gauge by using tipping-bucket method, and then called tipping-bucket rain gauge (TBR). The function of the TBR is to measure the amount of rainwater that falls on a certain surface of the earth with a certain time range as well. The amount of rainfall is generally measured using units of mm per time. To measure the intensity of rainfall in urban hydrology the most common instrument used is TBR. Because of the measurement principle, the intensity of rainfall and bucket size are parameters that affect the time resolution. TBR has been successfully designed and built. The rain gauge has been tested in the laboratory and in the field (BMKG Bandung). Testing is done by building a system-based microcontroller, and with a program specifically created for these purposes. This system is able to display of measurement and record data rainfall for 24 hours using database. The reading results of TBR are successfully measured, stored in the database, and to be sent and displayed on the Web.
