Current Sensors

Current sensors are crucial devices in various applications, such as electric vehicles, power supplies, and control systems. They are employed to measure and monitor the amount of electric current in a current-carrying conductor.

Hall effect sensors are a common type of current sensor. The Hall effect is a phenomenon in which a voltage difference is created across an electrical conductor, transverse to the electric current in the conductor and a magnetic field perpendicular to the current. The Hall effect sensor, often in the form of a Hall element, is placed in the magnetic field generated by the current carrying conductor. This magnetic field is proportional to the current flow, and hence by measuring this created Hall voltage, the sensed current can be determined.

Despite the different types and methodologies, all current sensors aim for high accuracy, fast response time, and low offset while maintaining a balance between cost and performance. Other considerations may include electrical isolation, temperature compensation, and response speed.
