1. Current sensor chip: ACS712ELCTR-05B, ACS712ELCTR-20A, ACS712ELCTR-30A;
2. Pin 5V power supply, onboard power indicator;
3. The module can measure plus or minus 5A/20A/30A current, corresponding to analog output 100mV/A ;
4. When no detection current passes, the output voltage is VCC/2;
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 the magnetic field when using it!
