SparkFun SEN-11005 Non-Invasive Current Sensor – 30A

This non-invasive current sensor (also known as a “split core current transformer”) can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor.

This particular current sensor will measure a load up to 30 Amps which makes it great for building your own energy monitor to keep your power usage down, or even building an over-current protection device for an AC load. This sensor does not have a load resistor built in, so in most cases it will be necessary to place a resistor across the output to convert the coil’s induced current to a very small measurable voltage.

  1. Peter Hinch

    I use this in an accurate power meter application measuring AC power in the range from 3KW down to a few watts. It works as specified in the datasheet. I’m seeing no significant noise pickup or phase error. Great product.
