ACS712 5A 5 Amp Current Sensor Module

The ACS712 5A Current Sensor Module is an easy-to-use sensor for measuring AC and DC current up to 5A. Ideal for Arduino, ESP32, Raspberry Pi, and other microcontroller projects, it outputs an analog voltage proportional to the current flowing through the load, providing precise and safe current monitoring.

Key Features:

• Measures current up to 5A (also available in 20A and 30A versions)
• Outputs analog voltage proportional to current for easy MCU integration
• Provides electrical isolation from the load for safer measurements
• Easy to use with microcontrollers like Arduino, ESP32, and Raspberry Pi
• Phoenix terminal connectors with mounting screws for secure wire connections
• Compact and lightweight design for DIY electronics projects

Pin Configuration:

Pin No.	Pin Name	Description
