A3144 Hall Effect Sensor Pinout

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.

A3144 hall effect sensor pinout.

From these pins first pin is power pin and is used for power on this sensor. In our case we will be using the a3144 hall effect sensor which is a unipolar sensor. 5v dc voltages are used for power on this sensor. The pinout of a hall effect sensor is as shown below.

Interfacing the hall effect sensor with arduino is really simple. Making the connections for the arduino hall effect sensor. The internal circuit diagram of the hall effect sensor module is given below. 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.

The hall effect sensor we will use in this circuit is an a1302 hall effect sensor manufactured by allegro. Arduino hall effect sensor pinout. Vcc gnd do ao. 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 vcc of the sensor is connected to arduino s 5v power pin. How to use the hall effect sensor module. 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. Allegro alldatasheet datasheet datasheet search site for electronic components and semiconductors integrated circuits diodes triacs and other semiconductors.

Figure a3144 hall effect sensor. Hall effect sensor module consists of four pins i e. Sensitive hall effect switches for high temperature operation a3141 a3142 a3143 and a3144 for new customers and applications. Pin configuration of a3144 hall effect sensor.

This ic can detect magnetic fields. Every a 3144 hall effect consist of three pins which are shown in figure 2. A hall effect sensor works on the principle of well hall effect. The gnd of the sensor is connected to the gnd pin on the arduino.

We will then connect this ic to an arduino so that we the arduino can read the voltage output by the a1302 and we can display the readings to the computer screen. 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.
