arduino AC / DC HALL EFFECT ANALOG CURRENT SENSING SENSOR ACS712 30A RANGE MODULE Electronic Components Electronic Hobby Kit

The Allegro ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, commercial and communications systems. The device package allows for easy implementation for the user Typical applications include motor control. load detection and management, switch mode power supplies, and over-current fault protection. The device is not intended for automotive applications. 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 66mV/A This module can measure up to 30A
