Line Tracker (Finder) Sensor

This is high performance line finder that is designed for line following robotic. It consists two parts - an IR emitting LED and an IR sensitive phototransistor. It can output digital signal to a microcontroller so the robot can reliably follow a black line on a white background, or vice versa. The sensor is Arduino compatible.

Feature

• Small size.
• 5V DC power supply.
• Indicator LED.
• Digital output.
• Distance: up to 3 cm
