Salinity Detection in Households Using Raspberry Pi 3b+: New Perspectives

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.
