4 Pin Hall Effect Sensor Circuit

Arduino forum using arduino project guidance 4 pin hall effect current sensor.

4 pin hall effect sensor circuit. Vcc gnd h and h. Alternative digital hall effect sensors. Each sensor output h and h is connected to a comparator lm339 which therefore gives a single output as shown in the circuit diagram above. And are connected to the inputs 2 inputs.

We can use this voltage to detect that whether the magnetic is placed near the sensor or. The ic has 3 pins 2 for the power supply and 1 for the analog voltage output. A hall effect sensor as then name suggests works with the principle of hall effect and is used to detect magnets. Each side of the sensor can detect one particular pole.

The hall sensor works on the principle of hall effect which states the whenever a magnetic field is applied in perpendicular direction to the flow of the current then a potential difference is induced. In this configuration the hall effect sensor will convert a magnetic field within a specified proximity and will convert it into a linear analogue signal across its out pin. Other analog hall effect sensors. List below are the specification sheets for the hall sensors used in my you tube video.

The south pole. This analogue signal can be easily used for driving a load or for feeding any desired switching circuit. Ugn3013 hall switch pdf file tl173c 12 volt ratiometric hall sensor pdf file ugn3503 5 volt ratiometric hall effect sensor pdf file honeywell ss466 hall latch pdf file pictured above are typical pin outs on hall sensors. The analog hall sensor module contains a hall sensor.

4 pin hall effect current sensor. A3141 a3142 a3143 us1881 oh090u. 4 your code 5 a schematic of your circuit including any support circuitry such as amplifiers 6 you say you measured 2 4v as some current. It features operation with traditional planar as well as vertical magnetic field direction.

The used motor has 3 hall effect sensors as any sensored brushless motor each hall effect sensor has 4 pins. The three sensors are supplied with 5v through 100 ohm resistor. Since i have 4 pin hall effect sensors i added an analog comparator i used lm339n quad comparator ic to each one so each sensor outputs 2 outputs. Non inverting and inverting of the comparator as shown in the circuit schematic below finally i got 3 outputs from the 3 hall effect sensors.

Complementary output hall effect latch sensor location with pin out and package dimension vk package to 92 4 pins hall chip location 276 xxx mh276 vk date code x x x year week ex 2011 year 8 week 108. A1321 a1302 ss495b asc712. The a1262 2d dual channel hall effect sensor ic is offered in a 5 pin sot23w surface mount package as well as a 4 pin sip through hole package. This is too vague.

A novel vdd recovery circuit allows the complete two wire fan control circuit to fit in a small four pin pb free package.
