Description:

ACS712 Current Sensor 5A-20A-30A is a Fully Integrated, Hall Effect-Based Linear AC/DC Current Sensor with a 30A rating. Current sensors are used to monitor the amount of power a circuit consumes. This current sensor module can handle AC or DC currents up to 5A, 20A and 30A modules. A single analogue output signal connects to your microcontroller to provide the sensor readings

The voltage of the VOUT pin indicates the current. Each 100mV indicates 1A of current. Therefore, 300mA would mean that 3A of current is flowing through the connectors.

Here’s how the ACS712 work:

  • Current flows through the onboard hall sensor circuit in its IC
  • The hall effect sensor detects the incoming current through its magnetic field generation
  • Once detected, the hall effect sensor generates a voltage proportional to its magnetic field that’s then used to measure the amount of current
Features: 
  • Low-noise analogue signal path.
  • 5µs output rise time in response to step input current.
  • 50 kHz bandwidth.
  • Total output error is 1.5% at TA= 25°C and 4% at –40°C to 85°C.
  • Small footprint, low-profile SOIC8 package.
  • 1.2 mΩ internal conductor resistance.
  • 2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8.
  • 5.0 V, single-supply operation.
  • 66 to 185 mV/A output sensitivity.
  • The output ratio is 66mV/A.
  • Output voltage proportional to AC or DC currents.
  • Factory-trimmed for accuracy.
  • Extremely stable output offset voltage.
  • Nearly zero magnetic hysteresis
  • Working Current: 10mA.
  • Onboard power indicator
  • PCB board size: 31 (mm) x13 (mm)

Package included: 1x ACS712 Current Sensor 5A-20A-30A
