Description1pcs ACS712 5A/ACS712 20A/ACS712 30A Hall Current Sensor Module ACS712 model ACS712 5A 20A 30A|Integrated Circuits| -
1. Current sensor chip : ACS712ELC-20A;2. pin 5V power supply, on-board power indicator ;3. The module can measure the positive and negative 20 amps , corresponding to the analog output 100mV / A;4. There is no sense current is passed, 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 !
