1. Current sensor chip: ACS712ELC-20A;
2. Pin 5V power supply, onboard power indicator;
3. The module can measure plus or minus 20A current, corresponding to the analog output 100mV/A;
4. When no detection current passes, the output voltage is VCC/2;
5. The current to be detected is connected in series into the terminal
5. PCB board size: 31(mm)x13(mm);
Note: ACS712 is based on the principle of Hall detection, please try to avoid the influence of magnetic field
