A Hall-effect current sensor board that reads up to 30A in either direction, AC or DC, and reports it as a plain analog voltage: 66 mV per amp, sitting at half the supply (about 2.5V) when nothing is flowing. The measured circuit passes through a 1.2 milliohm internal conductor that is isolated from the signal side to 2.1 kV, so your Arduino never touches it. Screw terminals take the load wires and a 3-pin header goes to 5V, GND and an analog input.
Key features
- Measures up to 30 A in both directions, AC or DC
- 66 mV per amp analog output
- Reads 2.5V at zero current on a 5V supply
- 2.1 kV isolation between load and logic
- 80 kHz bandwidth, 1.2 milliohm series resistance
- Screw terminals for the load, 3-pin header for the MCU
