Introduction Flood early warning information system serves as part of decision-making to determine disaster management policies of the government and as a material consideration of the community in knowing the location of the disaster and prepare for flood disaster. Therefore, to curb disaster risk, the government has encouraged private institutions and private sector to develop telemetry instruments in providing disaster early warning information[1]. The use of information systems based on mobile technology are now a trend among current users such as the use of applications based on android operating systems is very high[2]. 2. Materials and Methods Several studies have been conducted in the research and development of early warning systems based on mobile communication and information-based technologies. It is known that communication technologies involving mobile devices and machines are growing rapidly in the industrial and global world. [3]. Previous studies that have built prototypes using GSM communication-based technology models such as flood monitoring systems and SMS-based early warning [4], [5], [6]. The study resulted in the sending of flood height data using SMS using Arduino Uno intermediate and GSM module which ended with alarm at flood information system station. Besides flood warning system, Landslide warning system has been built based on arduino microcontroller and GSM module [10]. In general the research produced an efficient way of spreading an early warning message so that it does not require human presence to be informed when the possibility of a landslide is imminent. current development of early warning information systems has led to internet of things (IoTs) technology as the direction used for disaster risk management and environmental effects [11]. The use of internet-based technology has been done some previous research such as the use of Google Map as internet-based location information such as research of vehicle tracking system in real-time based on Google Map and Arduino Uno. [12]. In this study the system sends the coordinate data onto the vehicle for the GSM module to the user in the form of location based on Google Map displayed through Browser. ![](https://maker.wiznet.io/upload/ckeditor5/495107820%5F1664919085%2Epng) In the block diagram of the flood early warning information system as shown in (Figure 2) it can be explained that data sent by the flood detector remotely will be received by the wifi modem and processed on the PC computer. Data processing is processed in the mySQL database as the system management database using the sensor data table and location coordinates. The result of the relation between the two tables is integrated with PHP programming and Google Map API so as to produce output in the form of information system of early warning that will be accessed by android application ![](https://maker.wiznet.io/upload/ckeditor5/495107820%5F1664919118%2Epng) The work system of the flood detector system and flood early warning information system can be seen in (Fig. 3). There are several flood detection systems in several locations that send their data onto the flood information system server via the internet. The mobile application will receive information on real-time sensor data information on each flood detector based on location . ![](https://maker.wiznet.io/upload/ckeditor5/495107820%5F1664919161%2Epng) 3. Results and Discussions The design based on the design in (Figure 1) produces a flood detector system with sensors in the form of ultrasonic sensors, rain sensors, DHT11 sensors or temperature sensors, soil moisture sensors and GPS modules as shown in (Figure 4). The system as a whole consists of processor boxes containing temperature modules, U-Blox Neo 6m GPS module, Ethernet and Arduino Uno Microcontroller. While on the outside there is a rain sensor, ultrasonic sensors and humidity sensors. ![](https://maker.wiznet.io/upload/ckeditor5/495107820%5F1664919191%2Epng) On the outer side there is a construction of a flood-detecting pipe as shown in (Figure 5) made of a pantaloons pipe. On the inside there is a float as a reflective wave of ultrasonic sensors. The wave data transmitted from the echo module as a transmitter on the Ultrasonic Sensor is reflected back and received by the trigger module. The data received by the trigger is converted into altitude data by the microcontroller ![](https://maker.wiznet.io/upload/ckeditor5/495107820%5F1664919219%2Epng) Sensor data sent from the flood detection device to the flood early warning information system is stored in the mySQL database as shown in (Figure 6). In the information system database there are several fields including kode_station, water_level, weather_status, temperature, moisture_status, warning_status, lat_coordinate and lng_coordinate. ![](https://maker.wiznet.io/upload/ckeditor5/495107820%5F1664919262%2Epng) 4. Conclusions and Recommendations Based on the designed results, the Android based flood warning information system on the client side has been working as expected. Using ultrasonic sensors, rain sensor, soil moisture sensor, temperature sensor, Arduino Uno, u-Blox neo 6m GPS module and Ethernet module have been able to transmit flood station information data and flood location coordinates to client using android application. The flood information system stations to receive data onto the internet network of the flood detector system. With this prototype is expected to help information on the public in the form of flood information and its location. --- Source: https://maker.wiznet.io/mayuri/projects/flood-early-warning-information-system-for-multilocation-based-android/
