Introduction
ACS712-30A Current Sensor is used to measured the intensity of current. It contains ACS712ELC-30A chip ,based on Hall Effect. You should protect it from influence of magnetic field when using it.
Parameters
1.Chip:ACS712ELC-30A
2.5V Power Supply and Power Indicator On-board
3.This module can detect 30A positive and negative current,corresponding analog output at 66mV/A.
4.Output voltage is VCC/2 without current flowing.
Connection Diagram
Sample Code
#include <Wire.h> //invoking I2Clibraries coming with Arduino #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C lcd(0x27,16,2); int temp; // the setup routine runs once when you press reset: void setup() { // initialize serial communication at 9600 bits per second: lcd.init(); delay(100); lcd.backlight(); Wire.begin(); //initializing I2C lcd.clear(); //clear screen delay(100); lcd.setCursor(2,0); lcd.print("ACS712 TEST"); delay(200); Serial.begin(9600); } // the loop routine runs over and over again forever: void loop() { // read the input on analog pin 0: float current = analogRead(A0); temp=current; temp=temp-512; current=temp/13.6; //lcd.clear(); //clear screen // print out the value you read: Serial.print("current="); Serial.print(current); Serial.println("A"); lcd.setCursor(0,1); lcd.print("Current="); lcd.setCursor(8,1); lcd.print(current); lcd.setCursor(15,1); lcd.print("A"); delay(300); // delay in between reads for stability }

Result
In order to display data conveniently, add I2C LCD1602 Module. Then upload program and connect wires. After plugging in power, LED on this sensor is on and I2C LCD1602 Module displays the current intensity shown as below.
