ACS712 Current Sensor Module - 30A

A simple current sensor that can measure both DC and AC current. When the measured current is zero, the output voltage is half the supply voltage.

See the following pages for examples using a similar module: Measure AC current by interfacing ACS712 sensor with Arduino and How to measure Current using Arduino and ACS712 Current Sensor.

Note: The screw terminal included is not permanently soldered, if you want to use the screw terminal you will still need to solder it yourself. This screw terminal is rated for up to 20A, so only use it if your maximum current is below this. If you want to measure a higher current (max 30A), you can solder the cables directly to the module.
