INTERNET OF THINGS BASED FLOOD HEIGHT DETECTION

Abstract

Flooding is a disaster that often occurs in residential areas today, one of which is Jalan Teratai Gg Mawar I, Surabaya Village, Kedaton District, where this village is in an area close to a river. Floods can occur due to overflowing water, one of the causes is a lack of awareness among people who still throw rubbish in rivers and because there are broken embankments. Therefore, we need a flood warning system technology that can help provide information on flood disasters efficiently. One way is by utilizing internet of things (IOT) technology which can provide data information in the form of water level. This research aims to monitor water levels for information when a flood occurs. Ultrasonic sensors are used to detect water levels, and NodeMcu is used to process and send data to smartphones via the WhatsApp application. The results of this research show a system that can monitor the condition of the river water level repeatedly and when it reaches the specified height, the system will send a flood warning using the WhatsApp application installed on the smartphone, and a buzzer as an alarm signal and LED lights are used. as an indicator that can inform alert, alert and danger status. With this flood warning detection system, it is hoped that it can provide information when a flood occurs.
