4-Bit Line Hunting Sensor Follower Module for Arduino

4-channel infrared line tracking sensor module designed for line-following robots and autonomous vehicles. Detects black lines on white surfaces (or white on black) for precise path following.

SPECIFICATIONS:

• Working Voltage: DC 3.3V-5V

• Working Current: >1A power supply recommended

• Working Temperature: -10°C to +50°C

• Detection Range: 1mm to 60cm (adjustable)

• Output Signal: TTL level (direct microcontroller connection)

OPERATION:

• Infrared reflected back: Red LED on, output LOW

• No infrared reflection: LED off, output HIGH

APPLICATIONS:

• Line-following robots

• Obstacle avoidance

• Cliff detection (anti-drop)

• Edge detection

• Automated guided vehicles

PACKAGE INCLUDES:

• 1 x 4-Bit Line Hunting Sensor Module
