Sensor performance and features:
1. Current sensor chip: ACS712ELC-20A;

2.Measuring range: 20A

3. When the current is 0, the output is the power midpoint voltage, isolated.

4.Pin 5V power supply, onboard power indicator;

5. The module can measure positive and negative 5 amp current, corresponding to the analog output 100mV / A;

6.When no detection current is passed, the output voltage is VCC/2;

7. The current to be detected is connected in series to the terminal;

8.PCB board size: 3.1cm/1.2’’ x 1.4 cm/0.55’’;

9.Weight: 10.5g.

Note: ACS712 is based on the principle of Hall detection. Please try to avoid the influence of magnetic field when using.
