The ky 003 is a magnetic switch.
Hall magnetic sensor module.
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.
Specification 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.
It has a potentiometer to adjust the sensitivity of the sensor and it provides both analog and digital outputs.
The polarity of the magnetic field is of influence to the switching action.
The ky 024 linear magnetic hall sensor reacts in the presence of a magnetic field.

Magnetic sensors are designed to respond to a wide range of positive and negative magnetic fields in a variety of different applications and one type of magnet sensor whose output signal is a function of magnetic field density around it is called the hall effect sensor.
Frequently a hall sensor is combined with threshold detection so that it acts as and is called a.
Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications.
The analog hall sensor module contains a hall sensor.
If no magnetic field is present the signal line of the sensor is high 3 5 v.
Its output voltage is directly proportional to the magnetic field strength through it.
Hall magnetic sensor module.
If no magnetic field is present the signal line of the sensor is high 3 5 v.
On the other hand the analog output can measure the polarity and relative strength of the magnetic field.
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.
Keyes ky 003 arduino hall magnetic sensor module is a switch that will turn on off in the presence of a magnetic field.
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.
A hall effect sensor is a device that is used to measure the magnitude of a magnetic field.
This voltage can be used to detect whether the sensor is in the proximity of a magnet or not.
