4. Working Principle
The ACS712 uses the Hall effect principle for current detection and can output a voltage signal that is linearly corresponding to the current. Its workflow is as follows:
-
Power connection : Connect the power supply via VCC and GND. The module supports DC 5V operation.
-
Signal output : When current passes through, the module outputs a corresponding voltage signal to facilitate reading the current.
