Infrared break-beam sensors offer an efficient method for detecting motion with precision. This IR break-beam sensor operates effectively within a range of up to 50 centimeters, delivering a swift and stable response of less than 2 milliseconds. Its compact dimensions, measuring just 20 by 10 by 9 millimeters, make it ideal for installation in tight spaces, ensuring it integrates seamlessly where space is at a premium.
Designed to function in a broad temperature range from -25°C to 60°C, this sensor is versatile enough for various environments. Powered by a DC voltage of 3.0 to 5V, it can readily be paired with Arduino to facilitate simple motion detection, speed measurement, or timing applications, making it an asset in smart robotics competitions.
The sensor works by utilizing an emitter side that projects a beam of IR light that is invisible to the human eye. Positioned across from the emitter is the receiver, attuned to detect the same IR light. When an object that is not transparent to IR passes between the emitter and receiver, the "beam is broken," prompting the receiver to emit a signal. This clear and effective signaling process allows for reliable motion detection in a diverse range of projects.
