This non-invasive current sensor clamped around the supply line can measure up to 30 amps, and allow you to calculate how much current pass through it. It can be useful for building your own energy monitor or for building an over-current protection device for an ac load. Non-invasive ac current sensor can measure a load up to 30 amps ac source, simply clamp the current sensor on the live wire or neutral wire. The sensor measure the amount of current flowing through the wire. The output is a small ac signal which can be further use for energy meter application or for over-current protection of ac devices. To facilitate the application need the sensor has 3. 5mm jack on the output side. Popular application of non-invasive current sensor are like safe working on the high voltage electrical lines, protection of over current of the electrical device like ac motor, air compressor.
