Precision Line Tracking & Obstacle Avoidance
Whether you are building a competitive line-following robot or an automated guided vehicle (AGV), reliable surface detection is critical. The TCRT5000 Infrared Sensor Module utilizes advanced photoelectric technology to detect contrasts seamlessly. It effortlessly distinguishes black lines on a white background (or vice versa), making it the industry standard for robotics navigation, pipeline piece counting, and edge detection.
Dual Output Flexibility (Digital & Analog)
Adapt to any project requirement with versatile dual-output capabilities.
- Digital Output (DO): Connects directly to your microcontroller's IO port (ideal for external interrupts). It outputs a simple High/Low signal when a threshold is met, triggering instant action.
- Analog Output (AO): Provides real-time voltage changes based on the reflection intensity, distance, and surface color. Perfect for advanced users utilizing ADC conversion to map exact distances or grayscale gradients.
Clean Signals with LM393 Comparator
Say goodbye to jittery, unreliable sensor readings. This module is equipped with a wide-voltage LM393 comparator chip. It ensures the output signal is exceptionally clean with an excellent waveform, providing a strong driving ability that exceeds 15mA. Your microcontroller receives definitive data, eliminating false triggers.
Easy Integration & Safe Prototyping
Designed with makers in mind, this module operates on a flexible 3.3V to 5V power supply, making it universally compatible with 51 series, ARM, Arduino, and Raspberry Pi boards. The built-in power and status indicator LEDs allow for instant visual troubleshooting, while the M3 mounting hole ensures secure chassis installation in seconds.

FAQ Section
FAQ Section
- How do I configure my Raspberry Pi or ARM board to work with this sensor?For advanced control boards like Raspberry Pi or ARM, you must set the specific GPIO/IO port connected to the module's DO pin to Input Mode (Receiving Mode) in your code. If left in output mode, the sensor will not function correctly. (Note: Standard 51 series microcontrollers do not require this setup).
- What is the difference between the DO and AO pins?The DO (Digital Output) provides a simple binary signal (High/Low) based on a set threshold, perfect for basic line tracking or obstacle detection via interrupts. The AO (Analog Output) provides a fluctuating voltage based on the strength of the reflected infrared light, which is useful for calculating specific distances or detecting different shades of color using an ADC.
- Why is my module getting hot or failing to turn on?Warning: Ensure your wiring is 100% correct before powering on. Reversing the VCC (Positive) and GND (Negative) connections will instantly burn out the electronic components on the board. Always double-check your jumper wire polarity.
