 (1) One of the most frequently experienced natural disasters in
 Malaysia, particularly in its low-lying areas, is flooding. It poses a
 difficult challenge in terms of safety, destruction to property, and
 infrastructure which forcefully requires attentive action. Hence,
 the pre-emption steps that can be taken to monitor the situation
 are very important, as they can help alleviate the negative impacts
 to some extent. (2) The objective of this project is to design and
 build a basic flood sensor that can be assembled using low-cost
 electronic parts. (3) The sensor for this project was constructed
 using a float switch, a buzzer, and an Arduino microcontroller
 which were designed to trigger warning signals when the water
 level rises. The sensor was tested under various water levels in a
 simulated tank to verify its effectiveness. (4) The investigation
 showed that the sensor was working properly, as it was able to
 detect increased water levels and send a warning alarm within 3
 seconds. (5) This project demonstrates that it is possible to create
 a DIY flood alert system at a low cost that can be used by people
 living in areas prone to floods. In addition, it could be improved
 further, for instance by allowing mobile connectivity.
