DIYables Obstacle Avoidance Sensor for Arduino, ESP32, ESP8266, Raspberry Pi

Quick Overview

This 2-piece IR infrared obstacle avoidance sensor set provides object detection for Arduino, ESP32, ESP8266, and Raspberry Pi robotics projects. With adjustable detection range from 2cm to 30cm and a 35° detection angle, these sensors are perfect for collision avoidance, line tracking, and edge detection.

Ideal for obstacle avoidance cars/robots, automated vehicles, and line-following applications. The sensors operate on 3.3V-5V, making them compatible with most microcontrollers. Each sensor includes adjustable sensitivity via onboard potentiometer.
