This project was conducted as a group with the aim of designing a smart home system capable of responding automatically when water levels rise. The main problem studied is property damage caused by increasingly frequent floods, especially in high-risk areas.

Based on data from the National Disaster Management Agency (NADMA) and the Department of Statistics Malaysia (DOSM) (Appendix 7.1), the number of victims, property losses, and flood impacts have shown a significant increase in 2024. These statistics inspired our team to conduct research to develop an innovation that could help reduce the impact of floods on homes and residents’ safety.

The research hypothesis is that when the water level rises to a certain point, the system detects the change through a water sensor and subsequently activates an alarm system and an automatic house-lifting mechanism.

The methodology involves using a water level sensor connected to an Arduino Uno board, with a buzzer and LED as indicators. Experiments were conducted in stages by raising the water level to simulate real flood situations.

The results show that the system accurately detected changes in water level and responded consistently and promptly.

In conclusion, this innovation has the potential to reduce flood impacts and is suitable for application in smart home development in the future.
