Floods are one of the major disasters occurring all over the world, including Malaysia. It can lead to destruction of facilities, infrastructures as well as properties. Minimizing the risk of hazards and loss can be achieved by implementing several measures. Motivated from one of the biggest flood disasters ever occurred in the country, this monitoring system is developed as a means to reduce the risk of loss and damages. Monitoring rainfall rate may assist the community as it can provide early flood forecasting even though it cannot fully prevent the flood. Besides, it can give additional information on the probability of landslide occurrences. This paper presents the development of useful and reliable rainfall rate monitoring system for online hydrological stations in Kelantan. The whole processes in the development of this first prototype are conducted and performed using open-source software and tools such as Visual Basic and Quantum GIS (QGIS).Keywords

This paper outlines how the direction finder technology was exploited in the design of a device; capable of locating the where about of a UHF transmitter. The value of amplitude and frequency of the signal were employed in the determination of the signal source direction. The study emphasized on the utilization of low cost components. The assembled prototype offers 22.5˚ bearing coverage. The determination of the direction was achieved by differentiating the received frequency signal involving multiple antenna arrays. Direction of transmitter was determined by making the receiver antenna arrays emulating condition of motion with the use of antenna switcher. Received signals were converted into tones where larger signal amplitude translates to louder tone. Antenna arrays were arranged in specific manner where the tone volumes were compared and the direction within 360˚ position was determined. The result suggests that the system can provide the detection coverages up to 22.5 degree which is better than the existing solutions in terms of equipment selection, cost, and coverage.Keywords
