20A /30A Range DC AC Current Sensor Module ACS712 Module

The OKYSTAR OKY3312-30A is a current sensor module designed for measuring both alternating (AC) and direct (DC) current. Based on the ACS712ELC-30A Hall effect chip, it provides a simple and effective way to monitor current flow in a circuit up to ±30A.

Key Features
- Measures both AC and DC current within a ±30A range.
- Provides a proportional analog voltage output with a sensitivity of 66 mV/A.
- Outputs half the supply voltage (VCC/2) at zero current, simplifying integration with microcontrollers.
- Operates on a standard 5V power supply and includes an onboard power indicator LED.

As a Hall effect-based sensor, its accuracy can be influenced by external magnetic fields. For best results, position the module away from strong magnetic sources.
