1, the current sensor chips: ACS712ELC-30A;
2, pin 5V power supply, on-board power indicator;
3, the module can measure the positive and negative 30 amps, corresponding to the analog output 66mV / A;
4, no test current is passed, the output voltage is VCC / 2;
5, PCB board size: 31 (mm) x13 (mm);
Note: ACS712 Hall detection principle is based on using the magnetic field when you try to avoid this impact!
