5A ACS712 Current Sensor

The ACS712 5A Current Sensor Module is used to measure AC or DC current in an electrical circuit. It uses a Hall-effect sensor to detect the magnetic field generated by current flowing through its internal copper conductor and converts it into a proportional output voltage. The sensor can measure currents up to ±5A and provides an analog output that can be read by a microcontroller such as an Arduino Uno. It is suitable for applications such as battery monitoring, overcurrent protection, battery chargers, power supplies, and electrical power measurement projects.
