产品描述
1. Current sensor chip: ACS712ELCTR-05B, ACS712ELCTR-20A, ACS712ELCTR-30A;
2. Pin 5V power supply, onboard power indicator;
3. The module can measure positive and negative 5A / 20A / 30A current, corresponding to 100mV / A analog output
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 magnetic field when using it!
