1, the 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, corresponding to the analog output 185mV / A;

4, is not detected when the current through the output voltage is VCC / 2;

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

Note: ACS712 Hall detection is based on the principle of magnetic field when using please avoid this impact!
