Automated Urban Flood Detector Warning Device

Abstract

INTRODUCTION

Flood is a common hazard caused by an intense rainfall that generates quickly with little warning, sweeping everything in its path downstream. In line with this, an early flood warning device made from scrap with the application of Arduino UNO board was created to give early warning of the incoming flood and aware the people around.

METHODS

The flood warning device was composed of four components: the sensors, alarm/buzzer system, water level indicator, and the casing. The pipe was labeled and drilled and the water level indicator was placed onto the hole and then wires were soldered to be lengthened. The buzzer was placed into a bracket and the wires were soldered for connection purposes. Arduino UNO was programmed using Arduino 1.0.7. After the case was drilled from its corresponding labels to make pathways for the connection then, the Arduino UNO and the buzzer were attached to the case and the wires were connected according to its position. The device was tested to twenty students from Cavite National High School -Senior High in order to assess the buzzing sound of the device and its acceptability level. Statistical treatment Pearson r was used to determine the correlation between two variables.

RESULTS

Many of the Students who participated in testing the device agreed and give satisfaction with its functionality, acceptability level, and cost-effectiveness. Through the use of a statistical tool: Pearson r. there was a perfect negative correlation due to the computed value of -1 between in the quality of sound produced by the device and varying distance. The distance from the device and the sound produced of the device was inversely proportional to each other.

DISCUSSIONS

Overall, the functionality and cost-effectiveness of the device were highly acceptable. The researcher recommends the following for the better outcome of the device: (1) assess the functionality of the developed flood warning device on actual floods; (2) use the application of GPRS or SMS for the real-time update of the level of flood through the use of mobile phones; (3) and use additional components for the clear distinction of alarm in different flood water levels.
