Overview

Product Overview

The Infrared Obstacle Avoidance Module is a simple, Arduino-ready proximity sensor that helps your robot detect nearby objects and avoid collisions. It actively emits infrared light and reads the reflection to spot obstacles in front of a rover, smart car, or walking robot, making it a great “eyes up front” add-on for autonomous builds. A built-in potentiometer lets you adjust the detection distance (typically around 2 cm to 30 cm), and it outputs a straightforward digital signal when something is detected, so your code stays clean and fast with no analog conversion needed. With a convenient mounting hole, it’s easy to install on common 2WD/4WD chassis, and its quick response makes it useful for bots that need immediate stops or turns. It can also be used for short-range triggers in simple indoor automation projects like touchless dispensers or small DIY activators.

Questions & answers

Frequently asked questions

This infrared obstacle sensor is Arduino-ready and is commonly used with Arduino and ESP32 projects. It can also be used with Raspberry Pi-style builds when the digital output is connected appropriately for the controller’s input requirements.
The module provides a simple digital detection output, so most projects only need power, ground, and a digital input connection. ShillehTek modules are intended to be ready for quick wiring without extra assembly when headers are pre-soldered.
The sensor actively emits infrared light and checks the reflected signal from nearby objects. Its detection threshold is adjusted with the onboard potentiometer, and it outputs a digital signal instead of requiring analog distance conversion.
It is designed for short-range obstacle detection on rovers, smart cars, and walking robots. Mount it facing forward so the robot can detect nearby objects and trigger a stop, turn, or avoidance routine in code.
Use the onboard potentiometer to tune sensitivity and detection distance, typically around 2 cm to 30 cm. Object surface, angle, ambient infrared light, and mounting position can affect whether the module detects reliably.
