ACS 712 30A module

Features:1, the current sensor chip: 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 current flows through the detection, the voltage output 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!
