KY-032 IR Obstacle Avoidance Sensor Module for Arduino

The KY-032 IR Obstacle Avoidance Sensor emits infrared light forward and detects when that light reflects off an object within range when an obstacle is detected the output pin switches, signalling the microcontroller to take action. The detection distance adjusts from 2cm to 30cm adjustable via onboard potentiometers, allowing the sensitivity to be tuned to the specific environment and obstacle type the robot will encounter.

The ky 032 ir obstacle sensor module four-pin interface exposes negative, positive, signal, and enable lines. The EN pin allows the host microcontroller to switch the module on and off under firmware control. A white wall reflects more IR than a dark floor, so adjustable sensitivity is essential for reliable detection across different surface colours and ambient conditions.

The infrared obstacle avoidance sensor ambient light immunity reduces false triggers from sunlight and indoor lighting that cause simpler IR sensors to misfire. Operating from 3.3V to 5V the module connects directly to Arduino 5V or ESP32 3.3V GPIO pins without level shifting. The ky 032 ir sensor adjustable range suits robot bumper detection, conveyor end-stop sensing, and proximity trigger builds. This KY 032 ir sensor module is available on StemVolt, and its working on build obstacle detection and IR proximity sensing projects.
