AC Non-Invasive Current Sensor – 30A 交流電非侵入式電流感測器模組 SparkFun 原裝進口
Non-Invasive Current Sensor – 30A 這種非侵入式電流傳感器（也稱為“分體式電流互感器”）可以夾在電氣負載的電源線上，告訴您有多少電流通過它。它通過充當電感並響應載流導體周圍的磁場來實現這一點。通過讀取線圈產生的電流量，可以計算導體中流過多少電流。
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.
