- Infrared transmitter and receiver pair: This sensor module uses a pair of infrared transmitter and receiver tubes. It emits infrared light and detects obstacles in its sensing area. - Obstacle avoidance function: Suitable for robot obstacle avoidance, obstacle-avoidance cars, line counting, and black-white line tracking. - Adjustable sensing distance: The sensing distance ranges from 2 to 30 cm with a 35 degree detection angle. The effective detection distance is adjustable. - Easy to integrate: The output (OUT) can be conveniently connected to a microcontroller port, enabling it to drive a 5-V relay. - Applications: - Autonomous mobile robots that need obstacle detection to navigate safely. - Line counting and black-white line tracking systems. - Microcontroller projects requiring a simple IR obstacle sensor to control a 5 V relay.
