ACS712 20A Current Sensor Module
The ACS712 20A Range Current Sensor Module is comprised of a precise Hall circuit with a copper conduction path near the surface of the die. When an electrical current runs through the copper path, it creates a magnetic field that is then converted into a corresponding voltage by the Hall IC.
Ensuring and regulating the flow of current is a crucial factor in numerous applications, such as over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, and programmable current sources.
The ACS712 20A Current Sensor Module utilizes the ACS712 sensor to precisely measure both AC and DC current.
The maximum detectable AC or DC current is 20A, and it can be read through the analog I/O port of Arduino.
Do not introduce too many unnecessary variables.
