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.
This sensor uses the SFE Reed Switch - Magnetic Field Sensor. It can sense the magnetic materials within a detection range up to 75px.
The detection range and the strength of magnetic field are proportional.
It is useful for non-contact/waterproof type switches, position sensors, rotary/shaft encoders.
Note: this sensor needs to be used together with EASY plug control board.
Features
- Connector: Easy plug
- Sensing magnetic materials
- Detection range: up to 75px
- Output: Digital ON/OFF
- Detection range and magnetic field strength are proportional
Technical Details
- Dimensions: 41mm*20mm*18mm
- Weight: 4.4g
Connect It Up
Connect the EASY Plug Hall Magnetic sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.
Upload the Code
Below is an example code. Open or drag below code to Mixly Blocks and upload.
What You Should See
When magnetic beads are approaching to the sensor, the LED will be turned on. Otherwise, the LED is off.
Little Knowledge:
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.
Just need to change the LED state ON or OFF in the code, shown below.
Extension Experiment
Adding 4-digit LED Display
Hookup Guide
Connect the EASY Plug hall sensor, 4-digit LED display and red LED module to control board using RJ11 cables.
Upload the Code
Below is an example code.
What You Should See
When magnetic beads are approaching to the sensor, the LED will be turned on. Otherwise, the LED is off.
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.
