5A:

1. current sensor chip: ACS712ELC-05B;
2, pin 5V power supply, on-board power indicator;
3, the module can measure the positive and negative 5 amps, the corresponding analog output 185mV / A;
4, no current flows through the detection, the output voltage is VCC / 2;
5, PCB board size: 28 (mm) x13 (mm)

20A:

1, the current sensor chips: ACS712ELC-20A;

2, pin 5V power supply, on-board power indicator;

3, the module can measure positive and negative 20 amps, analog output 100mV / A;

4, when no current is detected by the output voltage is VCC / 2;

5, PCB board size: 31 (mm) x13 (mm);

Note: ACS712 Hall detection is based on the principle, try to avoid using the magnetic field caused by the impact of this!

30A:

1. The current sensor chips: ACS712ELC-30A;
2. Pin 5V power supply, on-board power indicator;
3. The module can measure the positive and negative 30 amps, corresponding to the analog output 66mV / A;
4. No test current through the output voltage is VCC / 2;
5. PCB board size: 31 (mm) x13 (mm);
