Abstract

Rainfall is an important parameter in the climate and weather monitoring system. Accurate and real-time weather monitoring will be very important in making decisions regarding agriculture, drainage, irrigation and emergency measures in the face of potential disasters. This research aims to provide information on rainfall monitored via an Android application. The Android application will be created using the Flutter framework developed by Google. The Android application was made at the Electronics and Instrumentation Laboratory, Physics Department, FMIPA, Sriwijaya University. Meanwhile, rainfall data collection was carried out in the Automatic Weather Station (AWS) field of the Physics Department, FMIPA, Sriwijaya University in July 2021 using a Tipping Bucket sensor. Rainfall data sent by the Tipping Bucket sensor is stored in a database. Changing data from the database into JavaScript Object Notation (JSON) form requires at least 1.2 seconds to display the data to the Android application on 4G and 3G network connections. If at the time the data is dis-played, the connection is on a 2G network, the Android application will show a continuous loading sign which indicates that no data has been taken from the database or can be said to be null data
