Raspberry Pi ACS 712 Current Sensor Module 5A Current Sensor Micro Controller Board Electronic Hobby Kit

HALL CURRENT SENSOR MODULE ACS712 30A MODEL The device consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage. The current sensor chips: ACS712ELC-30B; Pin 5V power supply, on-board power indicator; The module can be measured plus or minus 30 amps, corresponding to the analog output of 185 mV / A; There is no the detection current through, the output voltage is VCC / 2; PCB board size: 31 (mm) x13 (mm);
