Abstract

Every year, Malaysia experiences the devastating impact of the East Coast monsoon phenomena, particularly in coastal regions like Kelantan, Terengganu, Johor, KL, Selangor, and Pahang. Consequently, it becomes imperative to develop a cutting-edge flood monitoring device capable of issuing timely warnings to individuals in their homes. This innovative gadget utilizes advanced technology to provide accurate flood information and alerts to residents living in low-lying areas that are prone to frequent flooding. Floods are among the most destructive natural disasters, causing not only substantial material damage but also leaving a lasting psychological impact on the affected individuals. Therefore, the primary objective of this project is to design and assemble a circuit incorporating a microcontroller, warning device, and water level sensor. In the design of the circuit, an ultrasonic sensor has been employed to detect the water level. The output of this device consists of a buzzer and three LEDs: red, yellow, and green. When the sensor detects a rise in water level, the microcontroller transmits the data to the Blynk application, where the water level is displayed digitally and graphically. When the water reaches a certain level, the sensor is triggered, causing the LED and buzzer to activate. Additionally, the Blynk application sends a notification to the user in real-time. The key idea behind this project is to utilize the Blynk application to inform users if water levels are rising, while also incorporating solar panels to generate sustainable power for the device. By successfully implementing this project, the anticipated outcome is to empower people to proactively prepare for imminent floods.
