mCookie-Hall

Product number of mCookie Sensor—Hall:MSDS41

mCookie Sensor-Hall is a linear hall sensor, which can detect the strength and polarity of the magnetic field.

Sensor hall is a magnetic field sensor based on Hall effect.

Hall effect is a kind of magnetoelectric effect, which is found by Hall（A.H.Hall）on 1879 when he was studying the conduction mechanism of the metal.



Description of Sensor Pins

Hall Sensor
General Pin Out Sensor / Trinket's Pin Out
PIN1 (GND) GND
PIN2 (VCC) VCC
PIN3 (SIGNAL-A) Analog Input
PIN4 (SIGNAL-B) Not Connected
  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
  • Read more about the hub module.

    • Sensor CAD drawings: File:Sensor CAD.zip.
  • Function description
    • This sensor is 10-bit ADC（0~1023）, and the static value that the pin IO1 gets is 512;
    • The strength of the magnetism changes according to south and north poles;
      • If get close to the hall circuit from the back with the N pole, the output voltage will reduce, and the analog value will reduce（512~0）, too;
      • If get close with S pole from the back, the output voltage will increase and the analog input value will increase（512~1023）, too;
      • If from the front, the output state is opposite to from the back.
