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.
