This board implements a hall effect sensor in order to detect when a magnet comes close to it. The sensors are very precise and sensitive and that makes the board very reliable. In fact, It has the dimensions similar to standard switches but in addition to being more precise, this kind of sensor is even more stable because it can not be affected by dust, light, vibration or electromagnetic noise.
The most significantly difference bewteen this sensors and proximity/inductive sensors that are generally used, is that this ones works as normally closed circuit and that has a great advantage: in fact, a normally open circuit works in a kind of way similar to an antenna that will catch ambient noise (especially with most common control boards because they have high impedence on their pins). So, working with this kind of sensors will remove this problem and at the same time improves a lot the stability and immunity of the system.
(Best with Limit Switches Filter, check it out!)
This compact design makes it perfect for on-board mounting (only 3.00 cm!) and is fully compatible with most controllers; it has a very low current draw so it will not affect your system.
How they works? There are two possible states:
Untriggered state is default state of the board: LIMIT pin and GND are connected together and the led that indicates the state turns ORANGE. When the sensor is triggered, the circuit between LIMIT pin and GND is open. Led turns RED.
For the connections, the sensor mounts standard 2.54 header male pin.
