IR Sensor 5 Array with Obstacle and Bump Sensor is an advanced sensing module that combines five infrared (IR) sensors with obstacle detection and bump (collision) sensing capabilities. The 5-sensor array is mainly used for accurate line detection, allowing robots to follow straight lines, curves, and junctions with high precision.
Each IR sensor detects surface contrast (black/white), making it ideal for line follower robots. In addition, the obstacle sensor detects objects in front of the robot using reflected IR signals, while the bump sensor provides physical collision detection for immediate response.
The module provides digital outputs, making it easy to interface with Arduino, ESP32, and other microcontrollers. Sensitivity can usually be adjusted using onboard potentiometers. This all-in-one sensor board reduces wiring complexity and improves reliability in mobile robotics projects.
It is widely used in robotics competitions, educational kits, autonomous vehicles, and DIY automation systems. Suitable for students, hobbyists, and professionals working on intelligent robotic platforms.
