## Description

The ACS712 Current Sensor (5A) provides a simple way to measure AC or DC current up to ±5A. Based on the Allegro ACS712 Hall effect sensor, this module outputs a proportional analogue voltage that can be read directly by an Arduino or other microcontroller via an analogue input pin. With its low-resistance current path and electrical isolation, the ACS712 is well suited for over-current protection circuits, battery chargers, switching-mode power supplies, digital watt meters, and programmable current sources. Key Features ±5A Measurement Range – Detects both AC and DC current up to 5A Analogue Output – 185 mV/A sensitivity for straightforward ADC readings Hall Effect Sensing – Non-intrusive measurement with electrical isolation Low Resistance – Minimal impact on the circuit being measured 5V Compatible – Operates from 4.5V to 5.5V supply Specifications Supply Voltage: 4.5V – 5.5V DC Measurement Range: -5A to +5A Sensitivity: 180 – 190 mV/A (typical 185 mV/A) Sensor IC: ACS712ELCTR-05B-T Also Available ACS712 Current Sensor – 20A ACS711EX Current Sensor Carrier – ±31A ACS714 Current Sensor Carrier – ±5A ACS724 Current Sensor Carrier – ±50A SparkFun Low Current Sensor Breakout – ACS712 Ideal For Over-current protection circuits Battery chargers and monitoring systems Digital watt meters and power monitors Switching-mode power supply feedback Arduino and microcontroller current sensing projects Package Contents 1× ACS712 Current Sensor Module (5A)
