The Optum infrared sensor module detects obstacles at a distance of 2–30 cm and a detection angle of 35°. The distance is adjusted using the board’s potentiometer, while the OUT pin provides a continuous low-level signal when an obstacle is detected.
It uses an LM393 comparator and has mounting holes for 3 mm diameter screws. The OUT pin connects to a microcontroller input/output pin or can drive a 5 V relay. It is used in obstacle avoidance and line-following applications.
