The TCRT5000 IR Reflective Sensor Photoelectric Switch is a compact and reliable sensor module widely used for object detection, line following, and proximity sensing in electronics and robotics. It works on the principle of infrared reflection: the built-in IR emitter sends out infrared light, and the phototransistor detects the reflected signal from nearby surfaces.
With its high sensitivity and short-range detection capability, the TCRT5000 is ideal for applications such as line-following robots, rotary encoder sensing, and obstacle detection systems. The sensor is designed with a compact housing, making it easy to mount on PCBs or robotic platforms.
This sensor is commonly used by hobbyists, students, and engineers for DIY projects, automation, and embedded systems. Its low power consumption and stable performance make it a popular choice in robotic competitions and electronic learning kits.
