Water Quality Monitoring Robot based on Wireless Sensor System

Abstract

A good quality of water is an important to human health and aquatic ecosystem. Providing a continuous way to monitor the water quality can help the environment protection and prevent the water from contaminated. In this paper, the water quality monitoring system was designed based on a wireless sensor system by implemented with the three type of sensors that mounted into a mobile robot. These sensors are pH sensor, turbidity sensor, and temperature sensor. Then, the parameters involve are pH level (pH), turbidity (NTU) and temperature (^oC). Meanwhile, the data from sensors was sent to an Arduino microcontroller. This Arduino UNO was used as an interface between input and microcontroller to process the data that received from the sensors in real time and sent to the base station via wireless system. A reliable monitoring system can be established with appropriate calibration and precaution to get more accurate measurement of data. This was permitted the user to constantly monitor the quality of water accurately and to maintain the surveillance over extended period of time. The limitation of this wireless sensor is limited below 1000 m range from the base station. There are five (5) samples of water had been taken from the river and lake in Selangor area. The results show that all wireless sensors are capable to monitor the quality of water.
