Keyestudio 3 Channel Infrared Tracking Sensor Module IR Line Patrol For Arduino DIY Smart Car

The Keyestudio 3 Channel Infrared Tracking Sensor Module is an integrated line-following solution designed for DIY smart cars and robotics projects. Equipped with three TCRT5000 infrared tubes on a single board, it is perfect for students, educators, and hobbyists building autonomous line-patrol robots.

Reliable TCRT5000 infrared technology

The module utilizes three integrated TCRT5000 infrared tubes to detect surface colour variations. By measuring the reflectivity of infrared light, it converts the reflected signal strength into a usable current signal.

Precise line tracking logic

Designed specifically for line-patrol smart cars, this sensor outputs a HIGH level when detecting black lines and a LOW level on white backgrounds. This digital feedback makes it straightforward to program your microcontroller.

Adjustable detection sensitivity

The onboard adjustable trimpot lets you calibrate the sensor's sensitivity to match your environment. It operates reliably at a detection height of 0 to 3 cm from the track surface.

Convenient single-board integration

By combining three separate infrared channels onto one compact board, this design simplifies your robot's wiring and control logic. It features a standard 5-pin interface with a 2.54mm pitch for clean connections.

Easy mechanical mounting

The board includes two pre-drilled 3mm positioning holes, allowing you to mount the sensor securely to your smart car chassis. Weighing only 6.6g and measuring 42mm by 31mm by 7mm, it adds minimal bulk to your build.

Wide operating voltage range

Compatible with both 3.3V and 5V DC systems, this ROHS-compliant module integrates seamlessly with a variety of development boards. It is highly efficient and suitable for both educational and hobbyist DIY projects.
