Hall Current Sensor Module ACS712 model 20A
1 the current sensor chips: ACS712ELC-20A;
2 pin 5V power supply, on-board power indicator;
3 the module can measure positive and negative 20 amps, analog output 100mV / A;
4 when no current is detected by the output voltage 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.
