20A Range Current Sensor Module ACS712
The 20A ACS712 Range Current Sensor Module 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 in which the Hall IC converts into a proportional voltage. The maximum AC or DC that can be detected can reach 20A, and the present current signal can be read via the analog I / O port of Arduino.
Note: ACS712 is based on the principle of the Hall test, please use this field to avoid an impact!
