GP2Y0A21YK0F 10–80cm IR Distance Sensor with Cable

The GP2Y0A21YK0F IR Distance Sensor is a high-performance infrared sensor designed for accurate distance measurement within a range of 10cm to 80cm.

Using triangulation technology, this sensor provides a stable and reliable analog voltage output corresponding to the distance of an object. Unlike simple IR sensors, it is less affected by object color and ambient light, making it suitable for a wide range of applications.

This module comes with a connecting cable for easy integration with microcontrollers such as Arduino, ESP32, and Raspberry Pi. It is widely used in robotics, obstacle avoidance systems, and distance measurement projects.

Its compact size, low power consumption, and high accuracy make it a popular choice among students, hobbyists, and engineers.
