I. Introduction
The ACS712, a linear current sensor that depends on the Hall effect, is well-known for its accuracy and ease of use. By detecting the current, it transforms the magnetic field created by a current passing through a nearby conductor into a corresponding voltage output. The ACS712 is widely used in various industries, including power management, industrial automation, and automotive, due to its sturdy design and broad current measuring range.
II. ACS712 pin configuration
The ACS712 has three contacts: VCC, OUT and GND. These pins are usually clearly marked on the device, facilitating easy identification during circuit assembly and integration.
A. VCC (Voltage Supply Pin): The VCC contact is used to power the ACS712 sensor. A stable DC voltage within the specified operating range is required for proper operation. This pin is normally connected to the positive terminal of the power supply.
B. OUT (Output Pin): An analog voltage equivalent to the current passing through the sensor is provided by the ACS712’s OUT pin. To monitor and control current, this voltage signal can be directly interfaced to microcontrollers, analog-to-digital converters (ADCs), or other measuring devices.
C. GND (ground pin): The GND contact is the reference ground for the ACS712 sensor. It is connected to the negative terminal of the power supply and terminates the circuit, ensuring proper operation of the instrument.
