TCRT5000 IR Reflective Line Follower Sensor for Arduino Robots

IR Reflective Sensor Detects surface reflectivity using an infrared emitter and phototransistor for reliable line following.

Adjustable Sensitivity Onboard multi-turn potentiometer lets you fine-tune detection distance to suit different floor materials.

Digital and Analog Outputs Provides a DO switch for simple on/off triggers and an AO pin for proportional reflectance readings.

LM393 Comparator Includes a stable LM393 comparator for clean logic signals and reduced false triggers during motion.

Short-Range Detection Optimized for close-range sensing (typical detection up to the low tens of millimeters) on high-contrast lines.

Built-in Indicator LED Integrated LED lights when triggered to enable quick visual diagnostics without tools.

Non-Contact Limit Switch Operates as a contact-free optical switch ideal for wear-free endstop and object-detection tasks.
