Modelling and Simulation of Economical Water Quality Monitoring Device

Emerging as the mainstream of VLSI design, ASIC (ApplicationSpecific Integrated Circuit) technology is revolutionizing the design, manufacturing, and marketing practices in electronicsrelated industries [1]. Ground water is one of the important resource of water. In our country most of the people are depend upon it to fulfil their daily needs [2]. Since we have limited fresh water resources thus ground water can be used along with fresh water [3-5]. A sensor has been developed to measure the conductivity of a solution and is interfaced to the analog port of the microcontroller [6]. The microcontroller used here has many channel inbuilt A/D Converter which converts analog voltage signal to digital one. The sensor gives the value of the measured parameter and then the other subsequent values are calculated using equations shown in later in this paper and the results are displayed on LCD.
