Among the elements of automation, measuring equipment, as well as radio electronics, the Hall sensor, the principle of which is the effect of the same effect, occupies a special place. The meaning of this effect is based on the fact that during the premises of the conductor, in the form of a metal plate, in a magnetic field, the difference in potentials occurs. How is it used in the car? About this further in the article.

Hall sensor, principle of operation

These sensors have become part of many devices. Naturally, they are used for direct purpose, namely, the magnetic field voltage measure. Used in electric motors and even in ion engines rockets. Often, it is necessary to deal with the Hall sensor when using the vehicle ignition system.

Such simple examples: fluid level meters, contactless switches, reading magnetic codes, engine management, measurement in current power conductors and, of course, these sensors have changed to germes, because their main advantage is non-contact impact.

How are the Hall sensors and what is the contactless impact? The hall discovered that if they put a plate under voltage in the magnetic field, the electrons in this plate will be deviated perpendicular to the direction of the magnetic flux. As for the direction of such deviation, it is due to the polarity of the magnetic field. This phenomenon was called the Hall Sensor. Thus, the density of electrons on different sides of the plate will differ, which will create the difference of potentials. Her and catches the Hall Sensor.

Hall Sensor, Hall Car Sensor Scheme

The diagram of the sensor device is quite simple and can be slightly different from where the electronic device is installed and what is responsible for. In the picture below, you can see the process of the Hall sensor, for example, the car ignition system is taken.

Car Hall Sensor, Advantages and Benefits of the Sensor

The advantages of the Hall car sensor can be attributed to:

• The presence of an important parameter that allows you to change the frequency of the trigger (that is, the engine speed) in the absence of a displacement of the measuring point.
• Small dimensions.
• The presence of a "rectangular" signal from the device (professional term: a set of constant and a certain amount of node during its inclusion, there are no jumps in the voltage). This is a big advantage for electronics management.

Car Hall Sensor, Disadvantages and Negative Moments

• The Hall sensor is characterized by a higher cost relative to the magnetoelectric and theoretically, it is less reliable. This is due to the presence of an electronic circuit.
• Sensitive to interference electromagnetic fields arising in the food chain, but progressive technologies and production in large volumes are reduced to a minimum of these factors.

Hall sensor and car ignition, installation scheme and how it works

The Hall Digital Sensor includes a complicated compound from a semiconductor crystal, for example, an indium antimonide, which is installed on the aluminum footboard and is mounted directly into the sensitive part of the sensor. The plane of the crystal is directly perpendicular to the working part of the sensor, and the connecting conductions coming from the crystal are fastened with the handle to the electronic circuit, which is responsible for closing the output contacts.

The conductor is located to the magnet so that the power magnetic lines pass through the sensor crystal at a right angle, as a result of which the magnetic induction of a particular value occurs. The current passes through a crystal, which, during the room, the magnetic field is formed by electromotive force on the perpendicular sides of the semiconductor, which enters the scheme.

The Hall effect is observed when the conductor passes through a homogeneous magnetic field. Drifting unit electrons are charge carriers and activate the magnetic field for the use of Lorentz force (the force acting in the electromagnetic field on the charged particle) directly to these media. The body of the sensor is performed with a non-metallic material, so it is very gently affecting the field, not irritating magnetic waves.

Hall sensor how to connect a sensor to work

The electrical energy in the Hall sensor is activated by means of a switch (that is, the conductor), as a result of which it begins to emit a magnetic field. To make a high-quality connection, it is necessary to take into account the assignment of all the outputs of the switch:

• The first switch output is the output signal output. This connects the plus outlet of the ignition coil.
• The second and third conclusions of the switch are connected between themselves and are designed to connect with the mass.
• Fourth conclusion - connection with the battery.
• Fifth output - designed to power.
• Sixth output - the switch with the Hall sensor is connected through it.

How to check the operation of the Hall sensor

There are a number of ways to verify the help of the Hall sensor. Each car owner can choose the most appropriate option:

1. To check, take a working sensor (on a car disassembly or at a neighbor) and set it instead of a regular one. If problems disappear, then you will have to buy a new item.
2. At the output of the sensor, we measure the voltage using the tester. Voltage in a serviceable device will be changed within 0.4-11 V.
3. Create imitation of the Hall sensor, for which you remove the block with three plugs from the traver. Next, we turn on the ignition and connect the third and sixth switch outputs using the wire segment. The appearance of sparks will speak about the release of this sensor.

Council Prof.

When the Hall sensor is actively used in the vehicle design, the auto owner must regularly carry out checks and maintenance. The main thing is not to harm in the process of such checks, so disconnect the cable connector from the sensor when the ignition is turned off. Otherwise, the detail may fail.
