FLOOD MONITORING USING AUTOMATIC PACKET REPORTING SYSTEM APRS ON VHF

Flooding is a one of the devastating natural treat towards Malaysian which can cause a loss of life, money and property. Due to great damages to residential area, agriculture land, roadways and buildings, government have to spent a lot of money to recover all the damages which can affect the economy of the country. Therefore, in order to deal with this problem, one of the system can be improved is in the early warning flood detection system based on real time basis. "This paper presents the prototype design of a flood monitoring system which build by combining the water level sensor (conductance probe sensor) , monitoring LCD display, VHF 2m band handheld transceiver Baofeng UV-5R, Open Tracker USB terminal node controller board (APRS decoder), Arduino microcontroller and GPS module as a field station equipment (transmitter) at the catchment area while TPlink MR3020 internet modem, computer, RTL-SDR vhf tuner and another handheld radio transceiver as a monitoring station equipment (receiver).
