Sensor-Line Finder

The product number of Sensor-Line Finder is: MSDI41

Sensor-Line Finder is an IR reflection sensor module, which can serve as line finder.

The principle of black line detection is: the infrared emitting tube emits light ray to the surface of the road, the IR light will be reflected when touching the white road, and the receiving tube will receive the reflecting light.

Instruction of the 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-Line Finder 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.

Development

Program Download

• Download and unzip the program File:Sensor-Line Finder 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 "Sensor-Line Finder 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 diagram, connect the Sensor-Line Finder to the analog pin A0/A1 of Microduino-Sensorhub.

Result

• After download, open the serial monitor.
• The closer the obstacle, the smaller the returned analog value. So it can be used as obstacle avoidance sensor.
• When the sensor detects white and black with the same distance, the return value of white is smaller (around 100), and the one of black is larger (around 800). So it can be used as line finder.

Application

It can be used to detect obstacles and infrared emission, as a line finding sensor.
