The product number of mCookie Sensor—Gesture is: MSDI81

mCookie Sensor-Gesture is APDS9960.

Instruction of Sensor Pin

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.

• Connection
  • This sensor can be connected to the following interfaces of the core: A0~A7

Development

Program Download

• Download and unzip the program File:Microduino Gesture Test.zip

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.
