The a3144 hall effect sensor magnet detector switch for arduino is a switch that will turn on off in the presence of a magnetic field.
Hall effect sensor module.
Hall effect ic are contact less magnetically activated switches.
If no magnetic field is present the signal line of the sensor is high 3 5 v.
When the magnetic field rises above a threshold level the open collector output transistor switches on which pulls the logic compatible output low and illuminates the on board led indicator.

A hall effect sensor works on the principle of well hall effect.
The hall effect sensor works on the principle of the hall effect which states that whenever a magnetic field is applied in a direction perpendicular to the flow of electric current in a conductor a potential difference is induced.
The sensitivity of the sensor can be adjusted using a potentiometer.

An linear hall sensor consists of hall element linear amplifier and emitter follower and it outputs analog values if you add a comparator to linear hall sensor it will be able to output both analog and digital signals we call it as analog hall sensor.
Hall effect sensor module is used to detect the proximity of a magnet.
Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications.
The ky 003 hall magnetic sensor consists of a 3144eua s sensitive hall effect switch for high temperature operation a 680ω resistor and a led.
Commonly seen in industrial applications such as the pictured pneumatic cylinder they are also use.
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 ferromagnetic material.
Compatible with popular electronics platforms like arduino and raspberry pi.

If a magnetic field is presented to the sensor the signal line goes low at the same time the led on the sensor lights up.
This module incorporates an analog hall effect sensor.
Hall effect sensors detect the presence of a magnetic field and are commonly used for measuring the rpm of rotating assemblies where a magnet on the assembly alternately makes and breaks magnetic contact with the sensor as the assembly rotates.
This voltage can be used to detect whether the sensor is in the proximity of a magnet or not.
It is very much smaller in size.
6pcs hall effect magnetic sensor module 3144e a3144 hall effect sensor ky 003 dc 5v for arduino pic avr smart cars by mxrs.
Its output voltage is directly proportional to the magnetic field strength through it.
The output of the module goes high in the presence of a magnetic field and it becomes low in the absence of a magnetic field.
See the following figure for the schematic diagram of the analog hall switch sensor module.
