Description
The Infrared Proximity Sensor Module is a simple and reliable IR-based object detection module commonly used in robotics, automation, and embedded systems.
It works by emitting infrared light from the IR LED and detecting the light reflected back from an object using the photodiode. The onboard comparator then generates a clean digital HIGH/LOW output — making it extremely easy to integrate with any microcontroller.
This module is ideal for:
-
Line-following robots
-
Obstacle-avoiding robots
-
Automatic doors
-
Edge detection systems
-
IoT object sensing
-
Industrial automation prototypes
-
Embedded AI experiments
With an adjustable sensitivity potentiometer, you can fine-tune the detection distance based on your application.
