IEEE 802.15.4 based Water Quality Monitoring System

Internet of Things

Quality of water can be predicted using various parameters. Basically two kinds of impurities are present into water: Suspended impurities and Dissolved impurities. Water quality can be decided using different parameters like pH, Dissolved Oxygen[DO], Total Dissolved Solid and many more. pH and DO are the recommended parameter to be measured for deciding a quality of water at the fish farm. Here we present an application of wireless network: the sensing of DO for a fish farm. Application required sensor module for sensing a required data, wireless module for data transmission through radio channel and a gateway module as monitoring center. In this case, we have connected one master with two slaves using a transmission rate of 9600 b/s. The wireless transmission follow the standard IEEE 802.15.4 protocol and implement the routing protocol based on ZigBee standard. This is a qualitative and quantitative approach for a water quality monitoring. Main future of this application is that it is easy and effective way for doing real time water quality monitoring and it is extensible to any type of monitoring system just by interfacing an appropriate sensor.
