ACS712 Hall Current Sensor - Range and Pack Options

Add a Hall-based current input to your electronics project. This ACS712 board selection offers 5A, 20A and 30A versions with one-, five- and ten-piece quantities.

✅ Monitor supported AC or DC current - The sensor provides an analogue signal related to the current through its path.

✅ Choose the measurement range - Three versions let you match the expected current and interface sensitivity.

✅ Equip several sensing points - Multipack options provide boards for more than one circuit.

Match the Sensor Range to the Input Circuit

Choose the expected current range and design the controller's analogue input around the selected sensor's zero-current offset and sensitivity. The 5A version's conversion is not the same as the 20A or 30A version.

Check the actual board's terminals, current handling, supply and insulation limitations before use. A chip-level current range does not certify the complete board for hazardous circuits. The module is a sensing component, not an automatic protective cutoff.
