Hi guys welcome to today s tutorial.
Hall effect sensor circuit arduino.
Hall effect sensor arduino code.
Today we will look at how to use a hall effect sensor with arduino.
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.
This ic can detect magnetic fields.
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.
The gnd of the sensor is connected to the gnd pin on the arduino.
We have one input which is the sensor and one output which is a led.
This means that the output signal produced by a hall effect sensor is a function of magnetic field density around it.
The vout or signal pin of the hall effect sensor is connected to the arduino s interrupt pin digital pin 2.
This is done to pull the output of the hall effect sensor to 5v.
Whenever it will be placed in the region of magnetic field then it will detect it and will give us the output.
If you remember the arduino waterflow sensor tutorial we implemented earlier the main component of the water flow sensor is the hall effect ic.
Furthermore a 10k resistor is connected between the vcc and vout pins of the hall effect sensor.
A hall effect sensor is a sensor that varies its output based on the presence or absence of a magnetic field.
The hall effect sensor we will use in this circuit is an a1302 hall effect sensor manufactured by allegro.
