A3144 Hall Effect Sensor Pinout

Hall effect sensor module consists of four pins i e.

A3144 hall effect sensor pinout.

A3144 hall effect sensor pinout working alternatives datasheet. The pinout of a hall effect sensor is as shown below. How to use the hall effect sensor module. Every a 3144 hall effect consist of three pins which are shown in figure 2.

Arduino hall effect sensor pinout. Figure a3144 hall effect sensor. The internal circuit diagram of the hall effect sensor module is given below. Allegro alldatasheet datasheet datasheet search site for electronic components and semiconductors integrated circuits diodes triacs and other semiconductors.

Each side of the sensor can detect one particular pole. For the a3141 refer to the a1101 for the a3142 refer to the a1102 for the a3143 refer to the a1103 for the a3144 refer to the a1104 date of status change. The hall effect sensor we will use in this circuit is an a1302 hall effect sensor manufactured by allegro. Vcc gnd do ao.

Interfacing the hall effect sensor with arduino is really simple. If you remember the arduino waterflow sensor tutorial we implemented earlier the main component of the water flow sensor is the hall effect ic. The gnd of the sensor is connected to the gnd pin on the arduino. 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.

From these pins first pin is power pin and is used for power on this sensor. This ic can detect magnetic fields. Sensitive hall effect switches for high temperature operation a3144 datasheet a3144 circuit a3144 data sheet. Pin configuration of a3144 hall effect sensor.

In our case we will be using the a3144 hall effect sensor which is a unipolar sensor. The hall effect in short is a relationship between electric and magnetic fields through a semiconductor that allows electricity to flow when a magnetic field is applied within the vicinity of a given hall sensor. 5v dc voltages are used for power on this sensor. The vcc of the sensor is connected to arduino s 5v power pin.

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. Making the connections for the arduino hall effect sensor. A hall effect sensor as then name suggests works with the principle of hall effect and is used to detect magnets.
