Water Level Sensor at Parking Lot Using IoT Notification System

Abstract

The capital city of Malaysia experiencing flash floods more frequently and they do not always confine to the monsoon season. Kuala Lumpur had to face two kinds of flash flood around the year such as fluvial flash floods and drainage systems and it remains one of the most serious environmental problems. These phenomena have some unique characteristics such as they are sudden, unexpected and most of the time violent in nature. It shows that the roads and highways, houses, and vehicles are directly affected, damaged, and disrupted by flash floods. The problem is this situation really gives a lot of worries to netizens who live in the city. They need to always be alert about their cars leaving at the parking lot when the flood suddenly hits the parking lot and ruins their vehicles so this water level sensor at the parking lot is a really suitable warning system that will be provided to people when facing the flash flood. The method is the two major components consisting of the water level sensor and for the data, the transmission will use Bluetooth shield through the smartphone application. It will be integrated with a local webserver through which users can monitor the data from any device connected to the same Wi-Fi. Direct notification from smartphones can help the owner of the vehicles to always be alert when a flash flood occurs. This project is expected to solve problems faced by flash flood victims by implementing an early water level sensor mechanism at the parking lot so they will be able to save their vehicles. The objective of this research is to reduce the damages of the vehicles due to flooding at the parking lot and develop an early warning system for a flash flood at the parking lot using an IoT system.
