The a3144e us1881 is an integrated hall effect latched sensor.
A3144 hall effect sensor circuit.
There are two main types of hall effect sensor one which gives an analog output and the other which gives a digital output.
Thats nice but what does it do.
To recognize why these specifications are very important read even more.
How to use hall effect sensor.
Hall effect sensor module consists of four pins i e.
A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high.
The statement proposed says the hall effect is the production of a voltage difference the hall voltage across an electrical conductor transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.
Whenever the hall effect sensor is subjected to a magnetic field it toggles the relay as per the code.
A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high.
A hall effect sensor as then name suggests works with the concept of hall effect as well as is utilized to discover magnets.
Control a relay with arduino and hall effect sensor.
The working of this circuit is very simple.
Hall sensors works on the principle of hall effect proposed by edwin hall in 1869.
Applications of hall.
The digital output pin is connected to the output pin of the lm393 comparator ic while the analog pin is connected to the hall effect sensor.
This is primarily a magnetic switch that opens when placed near a magnetic field.
A reed sensor also works nicely but can be limited by the glass encapsulation and size.
Holding a magnet near the sensor will cause the output pin to toggle.
A3144 hall effect sensor belongs to the special class of sensors that measure the magnetic field.
There are two main types of hall effect sensor one which gives an analog output and the other which gives a digital output.
The hall effect sensor we will use in this circuit is an a1302 hall effect sensor manufactured by allegro.
Additionally the a3144 hall effect sensor datasheet can be located at the bottom of the page.
The circuit diagram for controlling a 5v relay module with hall effect sensor and arduino is shown below.
How to use the hall effect sensor module.
This ic can detect magnetic fields.
Where to make use of hall effect sensor.
Vcc gnd do ao.
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.
It is also mandatory to use a pull up resistor as shown below.
