Hall Effect Dc Current Sensor Arduino

The vout or signal pin of the hall effect sensor is connected to the arduino s interrupt pin digital pin 2.

Hall effect dc current sensor arduino.

Acs712 can measure current precisely and accurately if properly managed. 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. Acs712 is a cheap solution for current sensing in industry power sector and communication. Acs712 is a current sensor that can operate on both ac and dc.

The gnd of the sensor is connected to the gnd pin on the arduino. Introduction if you recall the previous arduino project i have discussed about measuring voltages greater than 5v with arduino using a voltage sensor. The advantage of using a hall effect sensor is that the circuit being sensed and the circuit reading the sensor are electrically isolated this means that although your arduino is running on 5v the sensed circuit can be operating at higher dc or ac voltages.

The acs723 sensor uses a hall effect sensor to output a voltage relative to the current flowing through the ip and ip pins. Current stock has red pcb the cs 100a is a hall effect current sensor board capable of measuring bi directional dc current flow. I have gone through various blogs on internet about interfacing acs712 current sensor with arduino and other microcontrollers. This is done to pull the output of the hall effect sensor to 5v.

This sensor can be used in ac and dc systems requiring isolation from the measured circuit and has low insertion loss and more connection options compared to conventional resistive current shunts. Acs712 current sensor interfacing with arduino for ac and dc current measurement. In this tutorial i am going to measure dc current using acs712 hall effect based linear current sensor and arduino uno. This tool consists of a series of precision hall sensors with copper lines.

Furthermore a 10k resistor is connected between the vcc and vout pins of the hall effect sensor. In this project. In this project we will discuss about acs712 current sensor how a hall effect based current sensor works and finally how to interface the acs712 current sensor with arduino. Simply speaking a hall effect sensor or ic detects motion position or change in magnetic field strength of either a permanent magnet an electromagnet or any.

A hall effect sensor works on the principle of well hall effect.
