ACS712 20A Range Current Sensor Module Overview
The ACS712 20A Range Current Sensor Module is a compact PCB module based on the ACS712 Hall-effect sensor, capable of measuring currents from –20 A to +20 A. It provides an analog voltage output proportional to the sensed current, making it ideal for real-time current monitoring in Arduino and microcontroller projects.
Key Features of ACS712 20A Range Current Sensor Module
- Current measurement range: –20 A to +20 A for high-load applications
- Sensitivity of 100 mV/A for accurate current readings
- Supply voltage: 4.5 V – 5.5 V DC, compatible with 5 V logic
- Analog voltage output easily interfaces with microcontroller ADC inputs
- Detects both AC and DC currents for versatile monitoring

How to Use ACS712 20A Range Current Sensor Module
Connect the module’s VCC pin to a stable 5 V supply and GND to ground. Wire the analog output (VOUT) to an ADC pin on your microcontroller or Arduino. Read the zero-current output (~2.5 V), then measure voltage shifts above or below this midpoint. Use the 100 mV/A sensitivity to convert the voltage difference into the corresponding current value.

Frequently Asked Questions
Can the ACS712 module measure AC currents?
Yes. The ACS712 sensor detects both AC and DC currents, outputting an analog voltage that varies around the 2.5 V midpoint proportionally to instantaneous current.
How do I calibrate the zero-current output?
With no load connected, read the module’s VOUT on your ADC. This should be approximately VCC/2 (around 2.5 V). Use this baseline value in your calculations to subtract offset before converting voltage difference to current.
What microcontroller voltage is required for the ACS712 module?
The module requires a 4.5 V to 5.5 V DC supply. Its analog output is centered at VCC/2, so use a 5 V-tolerant ADC input on Arduino or similar microcontrollers for accurate readings.
