The Elecrow Crowtail- IR Reflective Sensor 2.0 (CT0005IR) is a compact and efficient sensor module designed for proximity detection and object sensing applications. Utilizing an integrated infrared emitter and detector, the sensor emits infrared light and detects the reflected light to determine the presence of objects in its vicinity. This module is particularly useful in line-following robots, obstacle detection systems, and automatic data logging applications. The sensor operates effectively within a distance range of 4 to 15 mm, making it suitable for detecting small objects or surfaces. It features a built-in potentiometer, allowing users to adjust the sensitivity of the sensor to suit specific application requirements. The module is designed for easy integration with Crowtail-compatible systems, providing a straightforward solution for adding proximity sensing capabilities to your projects.
