Application of GSM Communication System on Flood Alarm Systems

Flood disaster has become a category of disaster that is prioritized nationally by the Indonesian government. To reduce the number of flood victims, it was emphasized to all parties to be able to provide disaster mitigation solutions in the form of both long-term and short-term programs. For short-term programs in disaster mitigation in this study aims to build a flood alarm system by utilizing GSM communication between flood detector systems and wireless flood alarm systems. Flood detector system is built using an ultrasonic sensor as a water level detector, Arduino Uno microcontroller as a data processor and a SIM900 sender GSM module as a data communication medium to a flood alarm system consisting of a GSM SIM900 receiver module, Arduino microcontroller and an electric alarm. This study produced a prototype flood alarm system that can ignite when the water level is> 5 cm. It is expected that this prototype can be utilized to contribute to government programs in the field of disaster mitigation.
