Description:
The ACS712 5A current sensor module is one of the best options for measuring both AC and DC currents. This current measurement module uses the Hall effect and can accurately measure currents up to 5 amps. The current you want to measure passes through the module's terminal, and a corresponding voltage is generated at the module's output. By analyzing this voltage through the ADC unit, the current can be easily determined.
The ACS712 current sensor uses an ACS712 chip from Allegro MicroSystems and can measure both positive and negative currents. It can measure current in the range of -5A to +5A. When no current flows through the module, the output voltage is 2.5V. For every 1 amp increase in input current, the output voltage increases by 185mV. These features make the current sensor suitable for Arduino and other microcontrollers.
The ACS712 module, with its analog output, converts the current signal into a voltage that can be measured by microcontrollers or Arduino, making it easy to use in various projects such as power consumption monitoring, motor control, and even building switching power supplies. This module also includes an LED indicator that lights up when powered on.
This module has diverse applications and, due to its high accuracy and simple operation, has become one of the most popular choices for current measurement projects.
Applications:
Energy consumption monitoring
Measuring current in DC and AC motors
Protecting electrical circuits from overcurrent
Battery Management Systems (BMS)
Power measurement and control projects
