mCookie-Hall

Product number of mCookie Sensor—Hall：MSDS41

mCookie Sensor-Hall is a HAL49E linear hall sensor, which can detect the strength 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，1855—1938）on 1879 when he was studying the conduction mechanism of the metal.



Description of Sensor Pins

  • Pins of the sensor:
    • PIN1: GND
    • PIN2: VCC
    • General signal pins:
      • PIN3(IO1): digital/analog signal
      • PIN4(IO2): NC(null)
    • Special signal pins:
      • If it is IIC: IO1/IO2 are respectively SDA/SCL.
      • If it is soft serial port: IO1/IO2 are respectively tx/rx.
  • Special to Sensor-Hall sensor pins
    • PIN1: GND
    • PIN2: VCC
    • PIN3(IO1): Analog signal input
    • PIN4(IO2): NC


Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.
