Original stock ACS712 module 5A range current detection board ACS712-05B Hall current sensor
ACS712 module 5A range current detection board
Product Features
Overview: This module belongs to a linear current sensor, designed based on the principle of Hall induction. It is equipped with a precise low bias linear Hall sensor circuit and copper located near the surface of the IC. When the current passes through the copper foil, a magnetic field is generated. The Hall element induces a linear voltage signal based on the magnetic field. After internal amplification, filtering, chopping, and correction circuits, it outputs a voltage proportional to the detected AC or DC current.
Product Applications
It can be applied in the field of motors, load detection and management, switching power supplies, and overcurrent fault protection.
Product wiring diagram
Accuracy range (Ip): It can measure a current of 5A, corresponding to an analog output of 185mV/A; When Ip=0A and no current is detected passing through, the output voltage is vCC/2, which is 2.5V. The calculation formula is VouT=2.5+0.185 * lp
