Abstract

Water is an excellent solvent and usually contains wide variety of dissolved minerals and other chemicals. Water molecules form hydrogen bonds with each other and strongly polar that is able to dissolve or suspend many different compounds. This paper focuses on the water storage monitoring system for households with pH sensor and turbidity sensor. The acceptable standard pH range for water storage tank is between 6.5 to 8.0. The data reading of the pH is monitored and if the pH ranges between acceptable range the water will continue to check water density using turbidity sensor and both measured values are further compared. If the obtained pH and turbidity values are between the acceptable range then the system displays the output as drinking water. If the pH and water density values are out of range and it is displayed as saline water.
