Connection Guide

Module connections:

  • VCC: 5V from Arduino
  • GND: Ground
  • OUT: Analog pin (A0)
Connect VCC to Arduino 5V pin
Use ADC pin for reading output voltage
Do not exceed 30A continuous
Keep sensor away from strong magnets

Reading Current

Arduino analog conversion:

  • Read analog value on A0
  • Subtract zero offset (512 typical) [citation:1]
  • Divide by sensitivity (13.6 for 30A version) [citation:1]

Formula: Current(A) = (ADC reading - 512) / 13.6

Simple Calculation - Easy integration into projects

Realtime Monitoring Continuous current tracking

Accurate to 1.5% at room temperature [citation:2]
Used in overcurrent protection systems

√ Available in bulk packs for multiple projects [citation:10]

√ RoHS compliant component

Troubleshooting

No output:

  • Check 5V power connection
  • Verify OUT pin connection
  • Avoid loose wiring

Inconsistent readings:

  • Add capacitor for noise filtering
  • Shield from magnetic interference
  • Avoid sharing power with motors
