The ACS712-30A Current Sensor Module is a compact Hall-effect board used to measure electrical current flowing through a circuit, supporting both AC and DC up to a 30A range. It gives a simple analog output that microcontrollers like Arduino, ESP32, or Raspberry Pi can read, making it a go-to component for hobbyists, makers, and anyone building a smart garden, automation rig, or pump-monitoring setup. If you want to know how much current a motor, pump, lamp, or appliance is drawing, this little module is one of the easiest ways to do it.
Key features
- ACS712 Hall-effect sensor for non-intrusive current sensing.
- Measures both AC and DC current within a 30A range.
- Simple analog voltage output, easy to read on any microcontroller's analog pin.
- Electrical isolation between the measured line and the signal side for safer wiring.
- Small board footprint that fits neatly into project boxes and breadboard builds.
Typical uses
- Monitoring the current of water pumps and irrigation motors.
- Building energy-monitoring and overload-detection projects.
- Arduino, ESP32, and Raspberry Pi learning and automation projects.
- Detecting whether a motor or appliance is running or stalled.
How to choose / tips
- Pick the 30A version when your load draws moderate-to-high current; lower-amp variants suit smaller loads.
- Keep the measured wire on the dedicated current-path terminals, not the signal header.
- Calibrate the zero-current reading in your code for cleaner measurements.
