Arduino Acs712 Ac Current Sensor Code

This is a simplified approach to my prior instructable regarding measuring ac current with the acs712 current sensor linksimplifications include.

Arduino acs712 ac current sensor code.

The difference in voltage from the side of the plate is the output of the sensor. Acs712 is a current sensor that can operate on both ac and dc. Ac current measurement using acs712 hall effect current sensor and arduino. Acs712 is a cheap solution for current sensing in industry power sector and communication.

When it comes to measuring current arduino or any other microcontroller needs assistance from a dedicated current sensor. Eliminating the special signal conditioning circuit board instead we re going to use the runningsta. As asc712 can be used for measuring either ac or dc currents arduino can be implemented to measure the same. Arduino uno interfacing with acs712 current sensor circuit diagram is given below.

This tool consists of a series of precision hall sensors with copper lines. You just need make change in code but the rest of the concept. In this tutorial you will learn how to interface acs712 hall effect current sensor with arduino and how to measure dc current using asc712 hall effect sensor and how to measure ac current using acs712 hall effect sensor. In this tutorial you will learn how to design alternating current measurement system using acs712 hall effect current sensor and arduino uno r3 but you can apply same concept to arduino mega pic microcontroller 8051 microcontroller or avr microcontroller.

Acs712 current sensor interfacing with arduino for ac and dc current measurement. The circuit is universal and all the above three codes for different versions of acs712 current sensor can work with the same circuit given below. May 13 2016 arduino tutorials ac acs712 ammeter arduino code current measurement meter manoj r. Https youtu be x9ka om9ibm this video explains how to measure ad or dc current of up to 30a using.

Thakur the acs712 measures current in two directions. It means that if we sample fast enough and long enough we sure to find the peak in one direction and the peak in another direction as the acs712 have 5 μs output rise time in response to. This sensor operates at 5v and produces an analog voltage output proportional to the measured current.
