Want to make a line following robot? Not a big deal now with this highly efficient 3 way Line Tracking Module. It has 3 TCRT5000 Infrared Line Tracking sensors with on-board comparator, LED indicators and other signal conditioning components. And yes it is Arduino compatible! This module uses Infrared to detect the line so it has anti-interference ability, visible light will not interfere its operation. The TCRT5000 is a reflective sensor which include an infrared emitter and phototransistor in a leaded package which blocks visible light. It has indicator LEDs on it, when tracing sensor senses a key signal, LED lights, otherwise off. Specificaions: High sensitivity Stable performance Operating voltage 5V Output low black line, a white line output high Exquisite workmanship, with indicator With fixed bolt hole for easy installation.
