Wireless acquisition system for water quality monitoring

Water is an important natural resource and is required in our day to day life. The proposed system aims to design a wireless acquisition system which is the basic building block of the water quality monitoring system. This paper explains the work carried out to design the embedded wireless monitoring system that can measure the turbidity and pH of the water remotely. The system is built using the Peripheral Interface Controller (PIC) microcontroller, which gives a low cost and low power water quality monitoring system with the intrinsic use of RISC type controller. The system consists of two sections, namely, Transmitter section, that collects the pH and turbidity readings from remote place, and, Receiver section, that collects transmitted readings using the ZigBee wireless communication protocol. The results are classified into three classes using the different pH and Turbidity levels to get a water quality index. The results are displayed on the LCD as well as on PC over different time periods.
