Abstract

Earthquake is a type of natural disaster that cannot be predicted accurately while flooding is the most common natural disaster where the effect vary greatly especially in terms of property damage. Therefore, a Disaster Alert System is proposed where the system could detect earthquake and flood disaster by using sensors and then send the alert message to the recipient with an image of water level condition through smartphone application. In this system, accelerometer is used to sense the vibration (earthquake) while ultrasonic sensor is used to sense the water level (flood). Then, both signals are transmitted into Raspberry Pi, where it is used as a controller in this embedded system. A medium range earthquake disaster and a low level to high level of flood disaster are measured by this system. In addition, a USB camera is used to capture the image of water level condition once the ultrasonic sensor is triggered and the image is saved in JPEG format. Next, Raspberry Pi is triggered by the input signals of both sensors and then the alert message is sent to the recipient's mobile phone with the saved image through Telegram messenger application which is pre-installed in the mobile phone. This will help to alert the users to take the safety precaution in a shorter period when the earthquake and flood disaster are happened in order to save their lives. The experiments on time needed for detecting earthquake and flood disaster, sending, receiving and displaying the message are conducted since time is a crucial parameter that will affect the efficiency of the victims to take the precaution measurement. The effectiveness of this system is demonstrated by the results of the experiments. It is believed that many innocent lives could be saved with the introduction of this system.
