TCRT5000 Infrared Reflective Sensor Module Line Track Obstacle Arduino

Description �� TCRT5000 Infrared Reflective Sensor Module | AuscomTech The TCRT5000 infrared reflective sensor module is a compact detection board designed for short-range reflective sensing, line tracking, and basic obstacle detection in Arduino and other microcontroller projects. It uses a TCRT5000 infrared emitter and receiver pair with an LM393 comparator to provide both analog and digital outputs. Sensitivity can be adjusted using the onboard potentiometer to suit different surfaces and detection distances. This module is commonly used in robot line follower systems, black and white surface detection, object sensing, paper detection, and general DIY automation projects. ⭐ Key Features TCRT5000 reflective sensor – Infrared reflection-based sensing for line tracking and surface detection. Dual output interface – Provides both digital switch output and analog signal output. Adjustable sensitivity – Multi-turn potentiometer allows precise threshold tuning. LM393 comparator – Stable signal processing with clean switching output. 3.3V to 5V operation – Suitable for Arduino, ESP32, ESP8266, STM32, and other controller platforms. Compact PCB design – Small board size with mounting hole for easy installation. TTL compatible digital output – Simple connection to microcontroller input pins. �� Technical Specifications Sensor Type: Infrared reflective sensor module Sensing Element: TCRT5000 Comparator: LM393 Operating Voltage: 3.3V to 5V DC Detection Distance: Approx. 1mm to 25mm Outputs: D0 digital output, A0 analog output Digital Output Type: TTL switch output Sensitivity Adjustment: Onboard potentiometer PCB Size: Approx. 32mm × 14mm Mounting: Fixed bolt hole Pinout: VCC, GND, D0, A0 �� Typical Applications Line follower robots Black and white line detection Obstacle detection Object presence sensing Paper detection systems Pulse sampling and position detection DIY robotics and automation projects ⚠️ Important Notes Detection performance depends on target surface colour, reflectivity, and distance. D0 is a threshold-based digital output set by the onboard potentiometer. A0 provides an analog signal level for applications requiring variable reflectance measurement. For best results, adjust sensitivity after installation in the final operating position. Suitable for low-voltage logic systems including Arduino and many 3.3V development boards. �� Package Includes 1 × TCRT5000 Infrared Reflective Sensor Module �� Recommended Accessories (Not Included) Arduino Uno or Nano – for sensor interfacing and project development Dupont jumper wires – for quick connection to controller boards Robot car chassis – for line tracking and tracing applications Breadboard or prototype PCB – for testing and permanent installation
