How It Works
The ACS712 5A Current Sensor operates based on the Hall-effect principle, where a magnetic field generated by the current flowing through the conductor interacts with a semiconductor material. This interaction generates a voltage proportional to the current passing through the conductor. The ACS712 module amplifies this signal and provides a corresponding analog voltage output. The output voltage is then read by a microcontroller, which calculates the current flow based on a known reference value.
The sensor operates from a 5V supply and has an output that is centered around 2.5V when there is no current. Positive currents cause the output voltage to rise, while negative currents cause the output voltage to fall. The output can be easily calibrated to provide accurate current readings for your application.
