ACS712 30A Hall effect isolated AC DC current sensor module

 for Arduino STM32 PIC Raspberry Pi, UK Stock

Uses ACS712ELC-30A current sensor IC

Requires 5v supply, onboard power LED

PCB size: 31mm x 13mm

No current output voltage is 2.5v

Can measure Positive / Negative 30A

Output voltage changes by +/- 100mv per 1A

Example:

1.5A DC current in one direction will give 2.6v (2.5v + 0.1v)

1.5A DC current in other direction will give 2.4v (2.5v - 0.1v)

1.5A AC current will give a 200mv (+/- 100mv) signal centered on 2.5v

30A DC current in one direction will give 4.5v (2.5v + 2.0v)

30A DC current in other direction will give 0.5v (2.5v - 2.0v)

30A AC current will give a 4v (+/- 2v) signal centered on 2.5v

ACS712 uses Hall detection for current measurement

  so avoid nearby strong magnetic fields
