  • Current sensor chip: ACS712ELC-30A.
  • Pin 5V power supply, on-board power status LED.
  • The module can be measured plus or minus 30A current, corresponding analog output: 66 mV/A.
  • No test current through, the output voltage is VCC/2.
  • PCB size: 31(mm) x 13(mm).

Note: ACS712 is based on Hall detection principle, please try to avoid the magnetic field, when using as it may impact the reading accuracy.
