“Water quality” is a term used here to express the suitability of water to sustain various uses or processes. Any particular use will have certain requirements for the physical, chemical or biological characteristics of water; for example limits on the concentrations of toxic substances for drinking water use, or restrictions on temperature and pH ranges for water supporting invertebrate communities. The main aim of the project is design a smart water quality monitoring system using arduino and blynk APP. In this project temperature sensor is used to measure the temperature of the water. PH sensor measures PH of water and turbidity sensor measures the amount of light that is scattered by the suspended solids in water. Ultrasonic sensor is used to measure the water level. The arduino will sends these measured sensors values to the user mobile into the blynk app
