ACS712 Current Sensor module 20A
1, pin 5V power supply, onboard power indicator;
2. When no detection current is passed, the output voltage is VCC/2;
3, PCB board size: 27.4 (mm) x11.8 (mm);
Note: ACS712 is based on the principle of Hall detection, please try to avoid the influence of magnetic field when using!
