Working Principle
- The ACS712 is a Hall Effect-based sensor.
- It measures current by detecting the magnetic field generated around a conductor.
- The module outputs an analog voltage proportional to the current being measured.
- For example:
- 0A Current: Output = 2.5V.
- +20A Current: Output ~ 4.5V.
- -20A Current: Output ~ 0.5V.
- For example:
Applications
- Motor control and monitoring.
- Battery management systems.
- Overcurrent protection.
- Renewable energy systems (e.g., solar).
- General-purpose current sensing in electronics.
