Preliminary Study of Water Quality Monitoring Based on WSN Technology

Water plays an important role in human daily life such as drinks of human, farming, livestock breeding and also manufacturing. However, urbanization modernization and industrialization had cause pollution to the clean water source for the usage agriculture. Therefore, it is vital to have a water quality monitoring tool which provides real-time water quality data and cover large area. Although the research of water quality monitoring system is widely done and applied, the current system is still expensive, small coverage and not user friendly. Moreover, most of the WQMS developed is not suitable for agriculture purpose due to the usage of unsuitable sensors. Thus, an affordable, large coverage and user friendly wireless water quality monitoring system with suitable sensors is proposed to assist the authority effectively in maintaining the health of the natural water source around the area. Here, a low-cost, large coverage and user friendly water quality monitoring system with multi sensor which is based on Wi-Fi Technology is presented. The process of designing the system involves three main parts which are hardware development, software development and also wireless network process. For hardware development part, different types of sensor will be employed and the sensors will be integrated with microcontroller. As for the software development, a few programming software is integrated for data acquisition, processing and displaying. Finally, for the wireless network process, wireless network module is used to for data transmitting and receiving while website is used to display the obtained data.
