Rainfall Information System Using Geometry Algorithm on IoT Platform

Rainfall is the amount of rainwater that falls on the surface of an area of square meters (m
²
), It means that rainfall of 1 millimetre (mm) is equivalent to 1 liter/m
²
, which means that rain characteristics vary from one location to others in an area of 1 meter in one area. In this case, rainfall measurement is only carried out for the entire region, even though rainfall in one area has a rainfall value that varies in each region. It is necessary to measure rainfall in each location point with different rainfall values in the region to determine the amount of rainwater. We need an online information system to calculate rainfall in real-time and input the rainfall data into the database. This system generates 100% accuracy in detecting the rain from the testing that has been carried out. The time delay in accessing the application is 2.5 seconds. With the rainfall measurement information system, the stakeholder will get information about the amount of rainwater more comfortable and real-time.
