Description:

• Current sensor chip: ACS712ELC-20A;
• Pin 5V power supply, on-board power indicator;
• The module can measure the positive and negative 20 amps, corresponding to the analog output 100mV / A;
• There is no the detection current through, the output voltage is VCC / 2;
• PCB board size: 31 (mm) x13 (mm);

Note: ACS712 Hall detection principle, when you use to avoid magnetic field impact this!
