Sparkfun Detailed Product Description:
The Infrared Obstacle Avoidance IR Sensor Module is a compact, affordable, and easy-to-use solution for non-contact object detection. It emits infrared light and detects reflected IR rays from nearby objects to determine the presence or absence of an obstacle.
This module has a digital output (Active Low) — the output pin goes LOW when an obstacle is detected. It includes onboard potentiometers to adjust the detection range and sensitivity, making it ideal for line-following robots, obstacle-avoiding robots, automation systems, and interactive installations.
Compatible with Arduino, ESP32, Raspberry Pi, STM32, and other microcontrollers.
