Today we will look at how to use a hall effect sensor with arduino.
Hall effect sensor circuit arduino.
Hall effect sensor arduino code.
If you remember the arduino waterflow sensor tutorial we implemented earlier the main component of the water flow sensor is the hall effect ic.
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.
This is done to pull the output of the hall effect sensor to 5v.
This ic can detect magnetic fields.
A hall effect sensor is a sensor that varies its output based on the presence or absence of a magnetic field.
The vout or signal pin of the hall effect sensor is connected to the arduino s interrupt pin digital pin 2.
The gnd of the sensor is connected to the gnd pin on the arduino.
Hi guys welcome to today s tutorial.
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.
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 works on the principle of well hall effect.
We have one input which is the sensor and one output which is a led.
Furthermore a 10k resistor is connected between the vcc and vout pins of the hall effect sensor.
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.
