1, The current sensor chips: ACS712ELC-05B;
2, pin 5V power supply, onboard power indicator;
3, the module can be measured plus or minus 5 amps, corresponding to the analogue output of 185 mV / A;
4, there is no the detection current through, the output voltage is VCC / 2;
5, PCB board size: 31 (mm) x13 (mm);
Note: ACS712 Hall detection principle, when you use to avoid magnetic field impact this!
