5/10Pcs ACS712 5A 20A 30A Range Hall Current Sensor Module ACS712 Sensors Module For Arduino DIY Electronic Kit

5A:
＞. pin 5V power supply, on-board power indicator;
＞. the module can be measured plus or minus 5 amps, corresponding to the analog output 66mV / 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!

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;
