Arduino Hall Effect Sensor Circuit

We have one input which is the sensor and one output which is a led.

Arduino hall effect sensor circuit.

This sensor breakout consumes power from arduino power source 5 and gnd. 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. The only primary difference is that a hall effect sensor requires a magnet to also be employed for it to detect changes while ir and ultrasonic sensors are able to function. The complete arduino code is just few lines and it can be found at the bottom of this page which can be directly uploaded to your arduino board if you want to know how the program works read further.

The vout or signal pin of the hall effect sensor is connected to the arduino s interrupt pin digital pin 2. Acs712 can measure current precisely and accurately if properly managed. I found that all of them are. Furthermore a 10k resistor is connected.

Hall effect sensor arduino code. Whenever it will be placed in the region of magnetic field then it will detect it and will give us the output. Hall effect sensor with arduino circuit and code hall effect sensor module interfacing with arduino this module is used to detect the presence of magnetic. In this tutorial i am going to measure dc current using acs712 hall effect based linear current sensor and arduino uno.

This ic can detect magnetic fields.

The vcc of the sensor is connected to arduino s 5v power pin. Interfacing arduino and acs712 hookup.

A hall effect sensor works on the principle of well hall effect. We will then connect this ic to an arduino so that we the arduino can read the voltage output by the a1302 and we can display the readings to the computer screen. A hall effect sensor can be used in most places where you would use an ultrasonic proximity detector or an infrared sensor to detect changes or movement in the environment. The hall effect sensor we will use in this circuit is an a1302 hall effect sensor manufactured by allegro.

Interfacing the hall effect sensor with arduino is really simple. That is the anode connected to the hall effect sensor and the cathode with the black line on the arduino side. As per the breakout application note hall effect current sensor connected with target load and output signal is connected with well known arduino s a0 analog input pin 0. The gnd of the sensor is connected to the gnd pin on the arduino.

I have gone through various blogs on internet about interfacing acs712 current sensor with arduino and other microcontrollers.
