1. The current sensor chips: ACS712ELC-05B. 2. pin 5V power supply, on-board power indicator. 3. the module can be measured plus or minus 5 amps, corresponding to the analog output of 185 mV / A. 4. there is no the detection current through, the output voltage is VCC / 2. 5. PCB board size: 31 (mm) x13 (mm). Note: ACS712 Hall detection principle, when you use to avoid magnetic field impact this!
