Pair of infrared transmitting and receiving tubes This sensor module uses a pair of infrared transmitting and receiving tubes. It emits infrared light and detects obstacles within its detection range. Obstacle avoidance capability Designed for robot obstacle avoidance, obstacle avoidance cars, line counting, and black/white line tracking. Adjustable detection distance and angle Detection distance can be adjusted from 2 to 30 cm, with a 35-degree detection angle. Easy integration and drive capability The output port OUT can be discreetly connected to a microcontroller port, and it can drive a 5V relay. Key benefits and use scenarios - Reliable obstacle sensing for mobile robots and autonomous vehicles to prevent collisions. - Supports line following and line tracking projects, including black/white line detection. - Simple 5V logic compatibility for straightforward MCU integration and relay control. Use scenarios - Mobile robot: use for obstacle avoidance to safely navigate environments. - Line-following robot: integrate with a microcontroller to count lines and track the black/white pattern. - Small automation: use the OUT signal to trigger 5V relays for controlling actuators or other devices.
