Arduino_KY-024_Linear_magnetic_Hall_sensors

Arduino_KY-024_Linear_magnetic_Hall_sensors


Hardware

  • D0 (Digital Signal) Arduino D3 Only needed for "Digital script"
  • + +5V
  • G GND
  • A0 (Analog Signal ) Arduino A0 Only needed for Analog script"

Digital

When the linear Hall sensor detects a magnetic signal Arduino LED (pin 13)  (and led on module) flashes Arduino.


Analog

Value depends on position of magnetic field
Without magnet 523, with magnet between 417 and 730

Arduino_KY-003_Hall_magnetic_sensor_module

KY-003 37-1 Hall magnetic sensor module 

Hardware

  • Pin  S                 D10
  • Pin middle (5V) +5V
  • Pin -                   GND -





Function

When the Hall sensor detects a magnetic field, Arduino LED (and the led on the sensor module) lights up.

Arduino_KY-025_Reed_module

Arduino KY-025 Reed module

My version of this module has
2 leds:   power led and sensor led
4 pins + , G A0 (analog out) and D0 (digital out)
one IC( comparator ) and some resistors an a variable resistor (potmeter)On the internet you can also find a digital output only version of KY-025.

Hardware

  • D0 (Digital Signal)                 Arduino D3 (Only needed for Digital )
  • + +5V
  • G GND
  • A0 (Analog Signal )        Arduino A0 (Only needed for Analog  )

Digital


Function (Digital)

If power connected to the module the power led is on.
When a magnet is close to the sensor also the sensor led on the module is on and the pin 13 led on the Arduino will go on also.

Analog

On The Net i could not easy find an example using the KY-025 A0 analog pin.
I cloned an existing analog sensor script and tried it.


Function (Analog)

The reed sensor can only be closed (with magnet) or open (without magnet)  !!
With magnet i get the value is 1,  without magnet  1023.  Perhap the value can be changed with the potentiometer. (I did not try this.)

Arduino_KY-021_Mini_magnetic_reed_modules

Arduino KY-021 Mini_magnetic reed module

A resistor is included on my version of this module.
For the test you need to keep a magnet ( not included in the 37in1 kit ) near the sensor.

Hardware

S         (signal) Arduino Pin 3
middle             +5V
-                      GND


Function

The reed contact is closes with a magnet near the sensor and the built in led on the Arduino is turned off (Pin 13)  Without magnet the led is on.

Arduino_KY-029_Yin_Yi_2-color_LED_module_3MM

Arduino KY-029 Yin Yi_2-color LED module 3MM

Same as KY-011 only different led size
Additional needed 330 Ohm resistor ( 2x)
On my version only the red led functioned the other was defective !

Hardware

  • Arduino pin 10 --> resistor 330 Ohm --> Signal pin of the module   (Green)
  • Arduino pin 11 --> resistor 330 Ohm --> Middel pin of the module  (Red)
  • Arduino GND  --> module -/GND
The circuit perhaps can work without the 330 Ohm resistor, however it is strongly recommended to add the resistors!

Arduino_KY-036_Metal_touch_sensor_module

Arduino KY-036 Metal touch sensor module




Module has a power led and a led indicating touch of metal.
A0 seems to contain some analog out signal also to indicate if metal is touched.
Module contains a variable resistor (sensitivity?)

Connect

  • D0          Arduino Pin 3
  • +            +5V
  • GND       GND
  • A0          (not connected / Analog signal) 

Function

If metal wire over the transistor is touched Arduino led (pin13) is switched on
