Wireless sensor network development in unmanned aerial vehicle (uav) for water quality monitoring system

Abstract

Abstract Based on the results of monitoring data by Badan Pengendalian Lingkungan Hidup (BPLHD) on 13 rivers that crossed Jakarta area in 2010 showed that both river water and ground water have high organic and inorganic pollutants. To tackle the pollution, government take a river water sample at waste disposal location periodically to examine its water content. The industrial waste disposal location point is not always easy to reach. At the certain condition, officers must ride raft boat or walk down the river to access that location. Besides taking a longer time, human safety factors are also become consideration. Based on these problems, in this research a wireless sensor network was developed in an Unmanned Aerial Vehicle (UAV / drone) using 912 MHz radio frequency. UAV in this research is equipped with various sensors to determine water quality, namely: PH, temperature, turbidity, Dissolved Oxygen (DO), and carbon dioxide. All sensors are integrated and monitored wirelessly using Universal Asynchronous Receiver Transmitter (UART) on the ground station. The telemetry system is designed to be able to send and receive data up to 1 KM distance in real-time. There are three general stages in this research, namely configuration design, manufacturing, and UAV flight test.
