Abstract

This development of a flood monitoring system consists of water level, rain detection and Blynk apps real-time monitoring and alert system. The microcontroller nodeMCU is used to control the system which consists of ultrasonic sensor and rain gauge sensor and write the data to Blynk apps via WiFi built-in. Monitoring dashboard and warning system were developed using Blynk application. This flood monitoring system is developed to monitor the water level and to measure amount of rain in real time and alert the user immediately when the defined alert condition occurs through the Blynk application. The system will be placed at area that prone to flood drainage system. The data are instantly collected and stored in a Blynk database for recording purposes. The objective of the proposed system is to send flood information using more efficient procedure thus the users will be receiving information about the flood earlier using Blynk application that can be access easily by users, with the help of WiFi built-in to establish the connection to the internet makes the system far more efficient compared to the existing system. The system however does not just stop there but proceed to give alert for three-level that are Safe level, Warning level and Danger level via Blynk application.
