A current sensor is a device that detects electric current in a wire, and generates a signal proportional to that current. The generated signal could be analog voltage or current or even a digital output.
- the current sensor chips: 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;
- no test current through the output voltage is VCC / 2;
- PCB board size: 31 (mm) x13 (mm);
