Early warning system for rapid flood at recreational area sites using LoRa network

Flood is one of the major disasters that affects many people each year in numerous places throughout the world. This flood disaster can occur anywhere, but the recreation area is the most dangerous. Therefore, an Io T early warning system for flood detection utilising the Arduino technology is suggested as a possible fix. The system is made up of a few sensors, including temperature, humidity, water flow sensor and ultrasonic ones. This research aims to develop a system that can contribute to collect data which will be used as an attribute to monitor and detect the water flow activity such as the water level and water velocity. Then to notify the potential occurrence of rapid flood. To implement this system, a System Development Life Cycle (SDLC) has been used as the methodology. Testing has been conducted by using method field testing at Puncak Janing Waterfall to evaluate the functionality of all sensors. All the data that has been taken is saved in the firebase database. The connection also used ESP32, where the coding was written and compiled using Arduino IDE software. This project has successfully achieved its objective where water level and water velocity can be monitored and stored in a firebase.
