Key Features of ACS712 30A Hall Current Sensor Module
- +/-30A Bidirectional Sensing: Measures both AC and DC current with a full-scale range of -30A to +30A, suitable for high-current applications like motor drives and power supplies.
- Analog Output Proportional to Current: Outputs a voltage centered at 2.5V (zero current) that increases or decreases by 66 mV per ampere - easily read by any microcontroller ADC.
- Galvanic Isolation (2.1 kV RMS): The Hall effect sensing provides complete electrical isolation between the high-current path and the low-voltage signal output, ensuring safety and noise immunity.
- Ultra-Low Insertion Loss: Internal conductor resistance of just 1.2 mOhm means negligible voltage drop and minimal power dissipation even at full 30A load.
- Fast 5 us Response Time: Captures rapid current transients and high-frequency waveforms with 80 kHz bandwidth - suitable for real-time monitoring and protection circuits.
- Simple 3-Pin Interface: Just connect VCC (5V), GND, and read the analog OUT pin - no complex communication protocols or additional components required.
- Screw Terminal Current Path: Heavy-duty screw terminals securely connect the load wiring for reliable high-current connections without soldering.
- Compact Breakout Board: Small form factor with onboard filtering capacitor and power LED, ready to drop into breadboard or project enclosure.
- Proven reliability with thousands of makers, students, and professionals across India
- Non-invasive Hall effect measurement eliminates the need for shunt resistors or current transformers
How It Works
The ACS712 module uses the Hall effect to sense the magnetic field generated by current flowing through an internal copper conductor. This magnetic field is detected by an integrated Hall sensor IC, which converts it into a proportional analog voltage output. At zero current, the output sits at approximately 2.5V (half of the 5V supply). As current flows in one direction, the output voltage increases above 2.5V; in the opposite direction, it decreases below 2.5V. With a sensitivity of 66 mV/A for the 30A variant, a current of +10A produces approximately 2.5V + (10 x 0.066V) = 3.16V, while -10A produces approximately 1.84V. Your microcontroller's ADC
