==Introduction==
The Hall sensor is based on Hall Effect. It can detect whether there is a magnetic object nearby or not. And it correctly tells you through digital output. <br>
This sensor uses the SFE Reed Switch - Magnetic Field Sensor. It can sense the magnetic materials within a detection range up to 75px. <br>
The detection range and the strength of magnetic field are proportional. <br>
It is useful for non-contact/waterproof type switches, position sensors, rotary/shaft encoders.<br>
<span style="color: red">'''Note: '''  this sensor needs to be used together with EASY plug control board. </span><br>

<br>

==Features==
* Connector: Easy plug
* Sensing magnetic materials
* Detection range: up to 75px
* Output: Digital ON/OFF
* Detection range and magnetic field strength are proportional

<br>
==Technical Details==

==What You Should See==
<br>[[File:ks0397 11-1.png|600px|frameless|thumb]]<br>
<br>
When magnetic beads are approaching to the sensor, the LED will be turned on. Otherwise, the LED is off.

<br>
<span style="color: red">'''Little Knowledge:'''</span> <br>
If you want to change another way, that is, once magnetic field is detected by sensor, LED is turned off; if no detecting magnetic field, LED is on.  <br>
Just need to change the LED state ON or OFF in the code, shown below.<br>

<br>
'''What You Should See'''<br>
When magnetic beads are approaching to the sensor, the LED will be turned on. Otherwise, the LED is off. <br>
How many times the magnet approaches to the sensor? You should be able to see the result showed on the 4-digit LED display or serial monitor.<br>
