8 Array Line Tracking Sensor Digital

The 8 Array Line Tracking Sensor Module is a digital IR-based sensor used in line follower robots to detect black and white lines on a surface. It contains 8 infrared transmitter–receiver pairs arranged in a row, allowing the robot to detect line position with high accuracy.

• Sensor Type: IR Reflective Line Tracking Sensor
• Number of Channels: 8 IR sensor array
• Output Type: Digital (HIGH / LOW)
• Operating Voltage: 3.3V – 5V DC
• Operating Current: ~50mA – 100mA (depends on LEDs)
• Detection Method: Infrared reflection (IR LED + photodiode)
• Output Interface: 8 digital outputs + VCC + GND
• Control IC: LM393 comparator (commonly used)
• Sensitivity Adjustment: Potentiometer (on some models)
• Mounting Type: PCB module mounting
• Working Surface: Black line on white surface
