The Hall Angle Sensor is a miniature 360 degree sensor which works based on the principle of the Hall effect. It is compatible with the DFRobot Gravity sensor interface, and works with a 5V DC power supply. The analog output is also 0~5V so it can work directly with Arduino.The Hall angle sensor wor..
What's the best way to detect the magnet? Use another magnet. But it's not sensitive enough and you need to feel it by yourself.
This Hall Sensor senses nearby magnetic objects and sends a signal via digital output.
Note: It's a omnipolar magnet dectector so that it can not tell two polarities apa..
