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 sense current is passed, the voltage output is VCC / 2;
5. PCB board size : 31 (mm) x13 (mm);
Note : ACS712 Hall detection is based on the principle , try to avoid using the magnetic field caused by the impact of this
