Daftar Isi:
- Rain has an important role in the hydrologic cycle. Rainfall (in mm) is the height of rain water which collected in a flat place and assuming that the water does not evaporate, does not sink in, and does not flow. This rainfall data is needed for agriculture and flood prevention, as used as an estimate for the construction of drainage channels, ditches, and irrigation. A device to measure rainfall is called rain gauge. The rain gauge that is designed in this thesis are expected to measure rainfall automatically using AT89S51 microcontroller which organize and process data from the load cell sensor. Weight data will be generated by the load cell in any specific period, then it will be converted into data in units of millimeters according to standards specified by the WMO (World Meteorological Organization). The processed data will be stored in external memory such as an MMC (Multi Media Card) and sent to the user's computer by using a mobile phone. The data that has been stored on the MMC in a ". txt” extention can be taken periodically by the user as a data back up and can be read directly by PC . If data is required from a remote area, the user can send instructions to a mobile phone that has been connected with a sensor to transmit the rainfall data at the time.
