TCRT 5000 Sensor

The TCRT5000 IR Sensor Module is a compact and reliable reflective optical sensor widely used in robotics and automation projects. It consists of an infrared LED and a phototransistor placed side by side, enabling accurate detection of surface reflectivity and object presence. The sensor works by emitting IR light and measuring the reflected signal, making it ideal for line-following robots, edge detection, and proximity sensing applications. Its fast response time, low power consumption, and easy interfacing make it perfect for beginners, students, and professionals alike.
