Frequently asked questions
What is the price of Current Sensor ACS712 AC/DC 30A Module in Egypt?
Current Sensor ACS712 AC/DC 30A Module currently costs 140 EGP in Egypt.
Where can I buy Current Sensor ACS712 AC/DC 30A Module in Egypt?
Current Sensor ACS712 AC/DC 30A Module is available from Circuits Electronics. Compare the offers above to find the best price.
What is the output at zero current?
The ACS712 output sits at about half the supply voltage at zero current (around 2.5 V with a 5 V supply). Currents in one direction raise the output above that point and currents in the other direction lower it.
How do I connect it to an Arduino?
Connect VCC to 5V, GND to GND and OUT to an analog input such as A0. The conductor being measured passes through the module's screw terminals in series with the load.
