Description
The KEYESTUDIO ACS712 Current Sensor (20A) is a reliable and easy-to-use module for measuring AC or DC current up to ±20A. Based on the Allegro ACS712 Hall-effect sensor, it provides accurate and real-time analog voltage output proportional to the current flowing through the circuit.
Ideal for power monitoring, load detection, and energy metering applications, this module is fully compatible with Arduino, ESP32, Raspberry Pi, and other development platforms.
