1, current sensor chip: ACS712ELC-20A;
2, pin 5V power supply, on-board power indicator;
3, the module can measure the positive and negative 20 amps, corresponding to the analog output 100mV / A;
4, there is no the detection current through, the output voltage is VCC / 2;
5, the PCB board size: 27.4 (mm) x11.8 (mm);
Note: ACS712 Hall detection principle, when you use to avoid magnetic field impact this!
