The ACS712 Current Sensor Module is a compact, Hall-effect based board used to measure electrical current in your circuits. The 5A variant reads both AC and DC current and outputs an analog voltage that's easy to connect to a microcontroller such as Arduino, ESP32 or Raspberry Pi. It's a favourite among students, hobbyists and makers who need a simple, isolated way to monitor current in a project, panel or small power supply.
Key features
- ACS712 Hall-effect sensor for current measurement.
- 5A measuring range, suitable for AC and DC current.
- Analog voltage output that's easy to read with any microcontroller.
- Electrical isolation between the measured line and the control side.
- Compact module with mounting holes for easy integration.
Typical uses
- Reading current draw in Arduino and ESP32 projects.
- Building energy monitors and overload protection logic.
- Battery charging and motor current monitoring.
- Educational electronics and prototyping experiments.
How to choose / tips
- Pick the current range that comfortably exceeds your expected load — the 5A version suits lighter loads.
- Calibrate the zero-current reading in your code for more accurate results.
- Keep the measured line wiring short and secure for cleaner readings.
