Fully Integrated, Hall Effect-Based Linear Current Sensor Module with 2.1 kVRMS Isolation and a Low-Resistance Current Conductor.
The current sensor chips: ACS712ELC-20B
Pin 5V power supply, on-board power indicator
The module can measure the positive and negative 5 amps, corresponding to the analog output 185mV / A
No test current through the output voltage is VCC / 2
PCB board size: 31 (mm) x13 (mm)
Note: ACS712 is based on the principle of the Hall test, please use this field to avoid an impact
