Non-Invasive Current Sensor - 30A

The Non-Invasive Current Sensor - 30A by Sparkfun is a split core current transformer that can be easily clamped around any electrical supply line to measure the current passing through it. The sensor acts as an inductor, responding to the magnetic field around the current-carrying conductor. By interpreting the current produced by the coil, the current passing through the conductor can be accurately calculated.

This sensor is designed to measure a load up to 30 Amps, making it an ideal tool for constructing your own energy monitor to manage power usage effectively. It can also be used to build an over-current protection device for an AC load. Please note that this sensor does not come with a built-in load resistor. Therefore, in most scenarios, it will be necessary to place a resistor across the output to convert the coil's induced current into a small, measurable voltage.

The Non-Invasive Current Sensor - 30A replaces the SEN-10341 model. It is a versatile and essential tool for any hobbyist, engineer, or professional looking to monitor and manage electrical current in their projects. With its non-invasive design, it offers an easy and safe way to measure current without the need for direct contact with the conductor.
