TCRT5000 IR Sensor Module for Obstacle Avoidance & Line Following
TCRT5000 IR Sensor Module ā Obstacle Avoidance & Reflective Sensor
The TCRT5000 IR sensor module is a reflective optocoupler that detects objects by emitting infrared light and measuring the reflection. It is commonly used in robotics for line following, obstacle avoidance, and edge detection. With an onboard comparator and adjustable potentiometer, it provides a clean digital output that integrates easily with microcontrollers.

Compatibility
This module works seamlessly with Arduino, ESP8266, Raspberry Pi, and any microcontroller that accepts 3.3Vā5V logic. The digital output can be read directly on a GPIO pin, while the analog output (AO) can be used with an ADC for precise distance measurement.
Wiring Notes
Connect VCC to 5V (or 3.3V), GND to common ground, and OUT to a digital input pin. Adjust the potentiometer clockwise to increase sensitivity until the signal LED just turns off at the desired detection distance. No external pull-up resistor is required.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the module works directly with Arduino boards. Connect VCC to 5V, GND to GND, and OUT to any digital pin.
How do I adjust the detection range?
Turn the onboard potentiometer clockwise to increase sensitivity (detect objects farther away) and counter-clockwise to decrease it. Use the signal LED as a guide.
Can I get an analog output for distance measurement?
Yes, the AO pin provides an analog voltage proportional to the reflected IR intensity. Connect it to an analog input on your microcontroller for more precise readings.
