Non-Contact Current Sensor Circuit Using Hall-Effect IC

When it comes to sensing current (Amps) linear Hall-effect devices are the best and the most accurate. These devices can sense and measure current right from a few amps to many thousands. Moreover it allows the measurements to be done externally without necessitating a physical contact with the conductor.
