Electrical conductivity sensors are devices used to measure the ability of a solution to conduct electricity. This property is influenced by the presence of ions in the solution, which can come from salts, acids, or bases. The sensor typically consists of two electrodes that are placed in the solution, and the conductivity is determined by measuring the current that flows between them when a voltage is applied. These sensors are commonly used in various applications, including water quality monitoring, agriculture, and industrial processes. By providing real-time data on conductivity levels, they help ensure optimal conditions for processes such as irrigation, chemical manufacturing, and environmental assessments.
