Description
he Infrared Obstacle Avoidance Sensor is a compact and adjustable distance sensor designed for applications like obstacle avoidance, line following, and object detection. It features an adjustable detection range between 2cm and 30cm, allowing for flexible integration in various robotic and automation projects.
Powered by 3.3V to 5V DC, the module includes a built-in LM393 comparator for stable signal processing and a 35 detection angle for reliable sensing across a wide range. Its simple design, low-interference operation, and plug-and-play usability make it an excellent choice for both beginners and advanced developers.
