Current sensors measure the flow of electric current through a conductor and provide real-time data essential for control, protection, and monitoring of electrical systems. They are used widely in applications such as automotive systems, renewable energy setups, industrial automation, battery management, UPS/SMPS, and grid infrastructure. Growth is driven by increasing adoption of IoT, energy efficiency demands, stricter safety/regulation standards, and advances in sensor technology like Hall effect, magneto-resistive and flux-gate sensors.
