Key benefits Enables seamless tracking with an 8channel search module and eight IR sensing sensors for full coverage. accuracy through eight clearly marked sensors from D1 to D8, with onmodule markings to distinguish sensors during setup, ensuring reliable results. Enhanced obstacle detection using obstacle cover sensors; voltage variation remains below 1V, with decreasing voltage values from D1 to D8 as obstacles approach, while operating on a stable 3.3V to 5V supply. Stable analog performance with D1–D8 analog output modes and a normal level after power on for reliable analog signaling. What makes it stand out Clear D1–D8 sensor labeling and corresponding module markings simplify installation, calibration, and maintenance. Compatible with 3.3V–5V systems and standard analog interfaces for easy integration into existing projects. Simple, userfriendly operation designed for fast deployment in prototypes and educational settings. Applications and use scenarios Autonomous robotics: obstacle avoidance and navigation in indoor environments for service robots and hobbyist robots. Prototyping and education: sensorarray experiments, teaching proximity sensing, and building demonstration projects. Automation and monitoring: proximity sensing and coverage detection in smallscale automation, asset protection, or interactive installations.
