SCT-013 100A Non-Invasive Current Sensor 2 Inch Aluminum Foil Self Adhesive Tape (20 Meter) The MQ-7 sensor module canThis non invasive current sensor (also known as a "split core current transformer") can be clamped around an electrical load's supply line to determine how much current is flowing through it. It accomplishes this by functioning as an inductor and reacting to the magnetic field created by a current carrying conductor. You may compute how much current is going through the conductor by reading the amount of current produced by the coil. This sensor
