Cytron Maker Line: Line Sensor For Beginners, MAKER-LINE


With 5 x IR sensors array, the Maker Line is able to track lines from 13mm to 30mm width. The line’s colour is selectable as light (White) or dark (Black).

Building a line following robot for a school project or competition? Or building an Automated Guided Vehicle (AGV) for industrial use? Maker Line is the right sensor for you. With 5 x IR sensors array, it is able to track lines from 13mm to 30mm width. Line colour is selectable as a light (White) or dark (Black) line.The sensor calibration is also simple. It is not necessary to adjust the potentiometer for each IR sensor. Instead, press the calibrate button for two seconds to enter calibration mode, sweep the sensors array across the line, press the button again and you are done. The calibration data is saved in EEPROM and it will stay intact even when the sensor has been powered off. Therefore, calibration only needs to be carried out once, unless the sensor height, line colour or background colour has been changed.Maker Line also supports dual outputs. There are 5x digital outputs for the state of each sensor independently, which is similar to conventional IR sensors. There is also one analog output where its voltage represents the line position. The analog output also offers higher resolution compared to the individual digital outputs. This is especially useful when high accuracy is required such as building a line following robot with PID control.


  • Operating Voltage: DC 3.3V and 5V compatible (with reverse polarity protection).
  • Recommended Line Width: 13mm to 30mm.
  • Selectable line color (light or dark).
  • Sensing Distance (height): 4mm to 40mm (Vcc = 5V, Black line on a white surface).
  • Sensor Refresh Rate: 200Hz
  • Easy calibration process.
  • Dual Output Types: 5 x digital outputs represent each IR sensor state, 1 x analog output represents line position.
  • Supports a wide range of controllers such as Arduino, Raspberry Pi, etc.
