arduino HALL EFFECT ANALOG CURRENT SENSING SENSOR ACS712 5A RANGE MODULE Micro Controller Board Electronic Hobby Kit

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. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy after packaging. Current sensor chip : ACS712TELC-5B Operating Voltage : 5V The Module outputs 185mV/A This module can measure up to 5A
