Current protection circuits, battery chargers, switching power supplies, digital watt meters, programmable current sources, etc. It is a current sensor used to detect and control current flow in a wide variety of applications. It has ACS721 integrated on it. It can detect AC or DC current accurately. The maximum detectable AC or DC can reach 20A, and the current current signal can be read through the analog I/O port of Arduino. Also this product 5A and 30A options are also available.
Using with Arduino:
Operating Voltage: 3-5V
Current Measurement Range: -20A~+20A
Sensitivity: 100mV/A
