Description:
The ACS712 5A Current Sensor Module utilizes a precise, low-offset linear Hall effect circuit with a copper conduction path near the surface of the die. When current flows through the path, it produces a magnetic field, which the Hall IC converts into a proportional voltage output.
This module supports accurate AC and DC current detection up to 5A. The output signal can be read using the analog I/O port of microcontrollers like Arduino, making it ideal for projects requiring current monitoring and protection.
Applications
- Overcurrent protection
- Battery charging systems
- Switch-mode power supplies
- Digital wattmeters
