Abstract

Flash flood disasters are natural phenomena in Malaysia that can occur anytime and anywhere. For safety precautions, a notification message should be sent to the people early to avoid any losses of property or life. This system is designed as an earlier flood alert system that can detect water levels using an ultrasonic sensor. The objectives of this research are to develop a system that can be aware of the water level of flood to the user and send a notification to people about the flood’s condition through the mobile application. NodeMCU, an ultrasonic sensor, and solar technology developed the system. This project focuses on monitoring water levels, using Wi-Fi as a medium to send warning notifications to people through mobile phones, and the accuracy of ultrasonic sensors using and without pipes. This prototype can send short warning notifications to Blynk apps. The average percentage error of the water level distance from the ultrasonic sensor with pipe was lower than without pipe, which was 2.55% and 3.11%, respectively. This system improved the notification message-sending method and detection of the ultrasonic sensor.
