LM393 IR Module.

The IR Obstacle Avoidance Sensor is a versatile and low-cost proximity module available at RoboShop BD. It uses a pair of infrared emitting and receiving tubes to detect objects in its path. When the infrared light hits an obstacle, it reflects back to the receiver, triggering a digital output signal. With its adjustable sensitivity and compact design, it is the primary choice for line-following robots, DIY security systems, and industrial object counters.
