A3144 Hall Effect Sensor Circuit

There are two main types of hall effect sensor one which gives an analog output and the other which gives a digital output.

A3144 hall effect sensor circuit.

The internal circuit diagram of the hall effect sensor module is given below. The hall effect sensor we will use in this circuit is an a1302 hall effect sensor manufactured by allegro. The a3144e us1881 is an integrated hall effect latched sensor. Vcc gnd do ao.

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. Thats nice but what does it do. Hall effect sensor module consists of four pins i e. There are two main types of hall effect sensor one which gives an analog output and the other which gives a digital output.

This is primarily a magnetic switch that opens when placed near a magnetic field. 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. How to use hall effect sensor. A3144 lt sensitive hall effect switches for high temperature operation.

How to use the hall effect sensor module. A3144llt sensitive hall effect switches for high. It is also mandatory to use a pull up resistor as shown below. A3144 works on the principle of hall effect thus called the hall effect sensor.

Sensitive hall effect switches for high temperature operation a3144 datasheet a3144 circuit a3144 data sheet. A3144 hall effect sensor belongs to the special class of sensors that measure the magnetic field. This makes for a robust presence sensor. Holding a magnet near the sensor will cause the output pin to toggle.

A3144eua sensitive hall effect switches for high temperature operation. A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high. A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high. This ic can detect magnetic fields.

A reed sensor also works nicely but can be limited by the glass encapsulation and size.
