IR Break Beam Motion Sensor With 3mm LEDs, Fast Motion Detection Up To 10 Inches, Open Collector Output For Easy Interfacing, Perfect For DIY Robotics, Automation, And Prototyping Projects
✔️ 25 cm range, 3.3-5V, open-collector output, 9.2 in cable
These infrared break-beam sensors provide a fast, simple motion-detection method for automation, robotics, and prototyping. By sending IR light across a gap to a receiver, they detect when the beam is interrupted by a non-IR-transparent object, triggering a digital signal. Use them for line-following robots, object counting, safety interlocks, or any project needing precise, eye-level sensing.
