## Description

  INTRODUCTION This is a breakout board for the fully integrated Hall Effect based linear ACS758 current sensor. The sensor gives precise current measurement for both AC and DC signals.The thickness of the copper conductor allows survival of the device at high overcurrent conditions. The ACS758 outputs an analog voltage output signal that varies linearly with sensed current.This current sensor enables you to monitor currents in your project every second for energy saving or circuit protecting purposes. This sensor can easily measure large current FEATURES  Arduino interface compatible 120 kHz typical bandwidth 3 µs output rise time in response to step input current Output voltage proportional to AC or DC currents Factory-trimmed for accuracy Extremely stable output offset voltage Nearly zero magnetic hysteresis Total output error improvement through gain and offset trim over temperature Monolithic Hall IC for high reliability Ultra-low power loss: 100 µΩ internal conductor resistance  SPECIFICATIONS  Operating Voltage(analog): 3.3-5V Peak Measuring Voltage:3000V(AC),500V(DC) Current Measuring Rang:-50~50A Sensitivity:40 mV/A Operating Temperature: -40~150°C Dimension:34x34mm(1.34x1.34")  DOCUMENTS  Wiki (50A Current Sensor) Sample code ACS758 datasheet Schematic  SHIPPING LIST  Sensor x1 Analog Sensor Cable (SKU:FIT0031) x1
