SHARP GP2Y0A02YK0F Infrared Distance Sensor 20cm to 150cm (Analog IR Proximity Sensor)

The SHARP GP2Y0A02YK0F is a long-range analog infrared distance sensor designed for accurate non-contact distance measurement and obstacle detection. Using infrared triangulation technology, it measures distances from 20cm to 150cm and provides an analog voltage output proportional to the detected distance. Unlike simple reflective IR sensors, its measurement is less affected by the target's color and reflectivity. The sensor is compatible with Arduino, ESP32, STM32, Raspberry Pi (with ADC), and other embedded development platforms, making it ideal for robotics, automation, and smart sensing applications.
