  • 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-Gesture 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.


Features

  • With high detection and good stability.
  • A linear hall sensor with a polarity.


Specification

  • Sensor voltage
    • 3.3V~5V working voltage
  • Size of the sensor
    • Sensor of the board: 23.5mm*13mm
    • 1.27mm-spacing 4Pin interface connected with sensorhub
    • CAD drawing of the sensor: File:Sensor CAD.zip
  • Function description
    • This sensor is 10-bit ADC(0~1023), and the static value pin IO1 get is 512.
    • The magnetic strength varies from north to south pole.
      • If approach to the hall circuit with N pole from the back, the output voltage will reduce, and so will the analog value(512~0).
      • If approach to the hall circuit with S pole from the back, the output voltage will increase, and the analog input value will increase(512~1023).
      • If approach from the front, the output state is positive.

Development

Program Download

Programming

  • Follow the Software Getting Started Guide.
  • Select the Board, Processor and Port.
  • Click [File]->[Open], browse to the project program address, and click "Microduino_Gesture_Test.ino" to open the program.
  • After confirming all these items are correct, click "→" to download the program to the development board.

Hardware Setup

  • Referring to the following picture, connect Sensor-Hall to the analog port A0 of Microduino-Sensorhub.



Result

  • After download, open the serial monitor.
    • If approach to the hall circuit with S pole from the back, the output voltage of the two ends of hall sensor is between 2.5V~5V, and the returned analog value is between 512~1023.
    • If approach to the hall circuit with the N pole from the back, the output voltage is between 2.5V~0V, and the returned analog value is between 512~0.
    • If from the front, the output state is positive.

Application

  • It can be used to detect the magnetic field strength.
