IR Sensor

This IR sensor module features adaptive ambient light capability, a pair of infrared transmitter and receiver tubes, a potentiometer for adjustable detection range (2-10cm), and a wide voltage range (3.3V-5V). When an object enters the detection zone, the infrared light is reflected back to the receiver, triggering the green LED and outputting a digital signal. This makes it ideal for various applications like robot obstacle avoidance, obstacle avoidance car, assembly line count, and black-and-white line tracking.
