ACS712 Current Sensor 30A
Out of stock
ACS712 Current Sensor 30A current sensor board is based on the Allegro ACS712ELCTR-30A bi-directional hall-effect current sensor chip that detects positive and negative flowing currents in the range of minus 30 Amps to positive 30 Amps. The board operates at 5V DC and the current flow through the sensor is converted to an output voltage starting at 1/2Vcc (or 2.5V) for no current flow and moves up 66mV per amp for positive current or down -66mV per amp for negative current.

ACS712 30A current sensor Price in Pakistan
The ACS712 30A current sensor module provides an analog signal for bidirectional AC or DC current measurement. It is commonly used in Arduino power monitoring, load testing, motor projects and basic over-current experiments where a microcontroller must read current flow.
When comparing an ACS712 30A current sensor price in Pakistan, check that the 30A version matches your required sensitivity and range. Calibrate the zero-current output in the final circuit, keep high-current traces and terminals secure, and follow suitable electrical-safety practices. This module should not be treated as a substitute for certified protection equipment.

Frequently Asked Questions
Can the ACS712 30A module measure both AC and DC current?
Yes. The ACS712 provides a bidirectional analog output that can be sampled for either AC or DC current measurement.
What is the sensitivity of the ACS712 30A version?
The 30A ACS712 variant typically provides about 66 mV per ampere around its zero-current midpoint. Calibrate the actual module in the final circuit.
Is the ACS712 module a replacement for a fuse or certified protection device?
No. It is a current-measurement component and should not replace suitable fuses, breakers, insulation or other required electrical-safety measures.
Why must the ACS712 zero-current output be calibrated?
Supply tolerance, sensor offset, temperature and ADC reference error can shift the midpoint, so measure the actual zero-current value in the final circuit.
How is AC current calculated from the ACS712 output?
Sample the waveform around its calibrated midpoint and calculate a suitable RMS value. The sampling rate and code must match the signal frequency and required accuracy.
