pThis invention deals with the automatic evaluation of water quality and monitoring through wireless personnel area networks. The system consists of multiple sensors of water quality testing, single-chip microcontroller data acquisition module, information transmission module, monitoring centre and other accessories. The waste waters collected from various industrial and domestic outlets were classified into respective units for monitoring. The parameters such as pH, Conductivity, turbidity, Dissolved Oxygen and Total Dissolved Solids (TDS) were measured by respective sensors. The water quality parameters were evaluated against the standards specified by IS: 10500 for drinking. The various parameters of water quality are automatically detected under the control of single chip microcontroller all day. The single chip gets the data, and then processes and compares them, for quality against standards. If the water quality is abnormal, the data's are instantaneously sent to monitoring centre by GSM network in the form of SMS./p
