- Operating Voltage: 4.5 to 5.5V
- Current Measurement: -20 to +20A
- Measurement Sensitivity: 66mV/A
The current sensor is based on the ACS172 current sensor, which can accurately detect AC or DC current. This current sensor has sensing range of -20A to +20A AC or DC current. The analog signal can be read via analog any I /O port on the Arduino.
