A3144 Hall Effect Sensor s works with the principle of hall-effect and is used to detect magnets. Each side of the sensor can detect one particular pole. It can also be easily interfaced with a microcontroller since it works on transistor logic.

So if you are looking for a sensor to detect magnets for measuring the speed of a moving object or just to detect objects then this sensor might be the perfect choice for your project.
