Android Application for Monitoring Soil Moisture Using Raspberry Pi

The growing population causes increasing clean water demand. This leads to a crisis of water demand due to high water consumption. During the dry season, water availability becomes increasingly rare for crop needs. To obtain maximum crop production, the availability of water should be sufficient. Therefore, an application for Android was created to assist monitoring of soil moisture. This application obtains data from the sensor which is connected to Raspberry Pi 3. This data will be sent to the server and displayed on Android application. LED indicator is provided to notify the water supply for the plants. The final result of this research is a system application development where a sensor with analog data can be converted into percentages and displayed in the Android application. From this percentage, users can set the indicator for the sensor to turn on the LED. Users can also view graphs from percentage data, manage plant data for the database, and set the application configuration.
