Sensing variable current is a frequent requirement in electronic systems, and the strategy for doing so is inherent in various applications themselves. Sensors are units that can determine physical phenomena and calculate them, in other words, they can provide measurable demonstrations of miracles within a specific range or range. A current sensor is a device that identifies whether the current in a wire or system is high or low and creates an indicator relative to it. Then it can be used to display the measured current in an ammeter, or it can be archived for further classification in a data acquisition system, or it can be used for control purposes. The current sensor is' interfering 'as it may cause a decrease in system performance when combined with certain sensors. There are various current sensors available to monitor alternating current or direct current, and measurement is required in many applications in industrial, automotive, or household fields.

Principle:

A current sensor is a device that detects and converts current to obtain an output voltage that is proportional to the current in the design path. When current passes through a circuit, the voltage at both ends of the path through which the current flows will decrease. Additionally, a magnetic field is generated near the current carrying conductor. The above phenomena have been applied in current sensor design technologies.

Current sensing element - inductive resistor:

Current sensing refers to the generation of voltage signals that are related to the current passing through the circuit. The conventional way to sense current is to insert a sensitive resistor in the current path. Then, we can place the sensed resistor anywhere in series with the circuit, whether it's a load or a switch. Therefore, the current detection device should be regarded as a current voltage converter.
