It represents a material's ability to pass a current. In a liquid, conductivity is a measure of a solution's ability to conduct electricity and can reflect the amount of dissolved or salinity of a water source, so it's an important parameter in water quality monitoring. DFRobot Gravity: Analog Electrical Conductivity Sensor PRO(K=1) is specially used to measure the conductivity in aqueous
