Non-invasive Current Sensor 30AThis non-invasive Current Sensor 30A AC current sensor is based on Current transformers, it transforms the big AC current to little, and then convert to voltage with the build-in resistor so users can get the AC current value via measuring the output voltage with any microcontroller such as Arduino. The split core type makes this sensor suitable for DIY usage such as energy monitoring for house & building.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 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.What is the difference between current sensor and current transformer?Current sensors can detect both AC and DC, external power supply is needed. Current transformers can only measure AC current and output signal is AC 5A or AC1A, external power supply isn’t needed. Common current transformer can only measure AC current.Video: Home Energy Monitor ProjectCheck out our other available sensors here Keep an eye on our website to avail the –Non-invasive Current Sensor 30A best price in BD (Bangladesh)
