ACS712 5A
This content will be shared across all product pages.
The ACS712 5A Current Sensor Module is a highly accurate sensor used to measure AC and DC currents. It utilizes the ACS712 Hall-effect sensor IC to provide a simple, reliable, and cost-effective solution for current sensing. This module can measure currents up to 5A and outputs a corresponding analog voltage that can be read by an Arduino, Raspberry Pi, or other microcontroller. It is ideal for applications in motor control, power monitoring, load detection, and overcurrent protection.
