ACS712-20A Current Sensor is used to measured the intensity of current. It contains
ACS712ELC-20A chip ,based on Hall Effect. You should protect it from influence
the magnetic field when using it.
- This module can detect 20A positive and negative current, corresponding analog output at 100mV/A.
- 5V Power Supply and power indicator on board
- Output voltage is VCC/2 without current flowing
