Current sensors measure the voltage or current of a power supply line and convert it into a value that can be accurately read. They are widely used in power management and monitoring systems to measure and control the amount, direction, and quality of electrical current. Current sensors can also be used to detect and measure irregularities, such as power overloads or errors. They are used in many industries, including automotive, medical, aerospace, industrial and consumer applications. Current sensors are available in analog or digital packages and come in a variety of sizes and shapes. They are commonly used in a variety of applications including motor control, load monitoring, power metering, and battery charging.
