ABSTRACT
Current sensors are devices that measure electric current in a circuit and convert it into a signal for easy monitoring and analysis. They are essential in applications like power management, motor control, renewable energy systems, and industrial automation. Common types include Hall effect sensors, shunt resistors, Rogowski coils, and fluxgate sensors—each with unique benefits in accuracy, bandwidth, and isolation.
INTRODUCTION
The ACS712 current sensor is a popular device for measuring electric current, operating on the Hall Effect principle to produce a voltage proportional to the current passing through its internal conductor. It enables accurate monitoring of both AC and DC currents by reading its analog output voltage and converting it into the corresponding current value using a microcontroller such as an Arduino.
COMPONENTS
To measure current using an Arduino and the ACS712 current sensor, the required components are an Arduino board, an ACS712 current sensor module, jumper wires, and optionally, a breadboard.
