The ACS712 20A Current Sensor IC (ACS712ELCTR-20A-T) provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die.

Applied current flowing through this copper conduction path generates a magnetic field that is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer.

A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy after packaging.


Features:

  1. The low-noise analog signal path.
  2. Device bandwidth is set via the new FILTER pin.
  3. 5 μs output rise time in response to step input current.
  4. 80 kHz bandwidth.
  5. Total output error 1.5% at TA = 25°C.
  6. Small footprint, low-profile SOIC8 package.
  7. 1.2 mΩ internal conductor resistance.
  8. 2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8.
  9. 5.0 V, single-supply operation.
  10. 66 to 185 mV/A output sensitivity.
  11. Output voltage proportional to AC or DC currents.
  12. Factory-trimmed for accuracy.
  13. Extremely stable output offset voltage.
  14. Nearly zero magnetic hystereses.
  15. Ratiometric output from a supply voltage.

Package Includes:

1 x ACS712 20A Current Sensor IC (ACS712ELCTR-20A-T).

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
