Description
The Infrared Obstacle Avoidance Sensor Module uses infrared reflection technology to detect nearby obstacles quickly and reliably.
When no object is present, the IR receiver detects no signal. When an object appears within range, the reflected infrared light triggers the sensor, changing the output state.
With adjustable detection distance and simple digital output, this module is ideal for Arduino, Raspberry Pi, and other microcontroller projects involving obstacle avoidance and object detection.
