Hall sensor with break outboard.
This sensor has a magnetic Gauss (GS) range from: +-1000.
The output is high at 1.6mV per Gauss , which is perfect for clutches and other short trow movements. The Hall sensor is really easy to connect.
Current consumption is also really low at 3.5mA.
When no magnate is present, the output will be at half the power supply voltage.
When a magnet come closer, you will get a positive or negative variation, depending on the orientation of the magnet.
The size is also very tiny, at around 1cm2
Connections
Connect 3.3V to + and Ground to -
The Signal wire S can be connected to an analogue pin on the Arduino.
