Hall Effect Sensor To-92 A3144

Description

Hall Effect Sensor To-92 A3144

1. A3144 Hall Effect Sensor as the 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.
2. It can also be easily interfaced with a microcontroller since it works on transistor logic.
3. So if you are looking for a sensor to detect magnet for measuring speed of a moving object or just to detect objects then this sensor might be the perfect choice for your project.
4.  There are A3144 Hall Effect Sensor one which gives an analogy output and the other which gives a digital output.
5. A3144 is a digital output hall sensor, meaning if it detects a magnet the output will go low else the output will remain high.
6. It is also mandatory to use a pull-up resistor as shown to keep the output high when no magnet is detected.
