Detail ACS712 20A Range Hall Effect Current Sensor Arus ACS 712 Module
The sensor gives precise current measurement for both AC and DC signals. The ACS712 outputs an analog voltage output signal that varies linearly with sensed current. The device requires 20VDC for VCC.
FITUR : * Brand new 20A Range ACS712 Current Sensor Module for Arduino * Current sensor chip: ACS712ELC-20A * Pin 20V power supply, on-board power indicator * The module can measure the positive and negative 20A, corresponding to the analog output 185 mV/A * There is no the detection current through, the output voltage is VCC/2 * Great for DIY project
