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.

|| 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.

- With high detection sensitivity and good stability
- With small size
- Size of the board: 23.5mm*13mm
- 1.27mm-spacing 4Pin interface connected with sensorhub
- The CAD drawing of the sensor: File:Sensor CAD.zip
- Technical parameters
- Can detect the distance form the obstacle, and the measuring range is about 3cm
- Can detect white and black, which make it can serve as line finder.
- This sensor can be connected to the following interfaces of core: A0~A7
- Referring to the following diagram, connect the Sensor-Line Finder to the analog pin A0/A1 of Microduino-Sensorhub.
- 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.
It can be used to detect obstacles and infrared emission, as a line finding sensor.
