Salinity detection in households using raspberry Pi 3b+

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 between6.5to8.0.Thedata 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 value sare 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.
