Hall Current Sensor Module ACS712

Hall Current Sensor Module ACS712 5A 20A 30A

Product Description:
This is a breakout board for the fully integrated Hall Effect based linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals. Thick copper conductor and signal traces allows for survival of the device up to 5 times overcurrent conditions.
The ACS712 outputs an analog voltage output signal that varies linearly with sensed current. The device requires 5VDC for VCC and a couple of filter capacitors. Please keep in mind that though the ACS712 is rated for 2.1kV isolation, the PCB it is on is not designed for that type of voltage. Please keep that in mind if you are using this breakout in high voltage applications.

5A
The current sensor chips: ACS712ELC-05B;
Pin 5V power supply, on-board power indicator;
The module can be measured plus or minus 5 amps, corresponding to the analog output of 185 mV / A;
There is no the detection current through, the output voltage is VCC / 2;
PCB board size: 31 (mm) x13 (mm);
Note: ACS712 Hall detection principle, when you use to avoid magnetic field impact this!

20A
Current sensor chip: ACS712ELC-20A;
Pin 5V power supply, on-board power indicator;
The module can measure the positive and negative 20 amps, corresponding to the analog output 100mV / A;
There is no the detection current through, the output voltage is VCC / 2;
PCB board size: 31 (mm) x13 (mm);
Note: ACS712 Hall detection principle, when you use to avoid magnetic field impact this!
