how can we distinguish between acs712 for 20A and 30A. Is there any labeling on the sensor module to know whether it is 20A or 30A type?

Hi,The ACS712 device comes in three variants, providing current range of±5A (ACS712-05B), ±20A (ACS712-20B), and ±30A (ACS712-30A). The ACS712-05B can measure current up to ±5A and provides output sensitivity of 185mV/A (at +5V power supply), which means for every 1A increase in the current through the conduction terminals in positive direction, the output voltage also rises by 185 mV. The sensitivities of 20A and 30A versions are 100 mV/A and 66 mV/A, respectively.To read these numbers you would require a good magnifying glass though :).

Is it possible to measure Earth Leakage Current with it ?

Yes .. We can measure the earth leakage current.. It's possible

it is compatible with arduino uno ?

For very slow speed it is OK. but for high speeds we have to use other platform like Raspberry Pi.

Can i directly connect it 230 v supply

Yes you can connect it to 230v supply but maximum current should not be as it's specifications like 30A,20A,5A

Nice and usefull

Ofset voltage is there so current is not 0.00 u need to eleminate this ofset Voltage in coding and if coding is good then its give accurate value 2.5 volt its ofset voltage good for both ac and dc , i test it in AC voltage with 200 watt blub with arduino and serial monitor and compare with electeical Enargy Meater with same 200 watt bulbs
