SHARP GP2Y0A21YK0F IR Analog Distance Sensor 10cm to 80cm (Infrared Triangulation Sensor)

The SHARP GP2Y0A21YK0F is a high-precision analog infrared distance sensor designed for non-contact distance measurement and obstacle detection. Using infrared triangulation technology, it accurately measures distances from 10cm to 80cm while being less affected by the color or reflectivity of the target compared to conventional IR reflective sensors. The sensor provides an analog voltage output proportional to the measured distance and is compatible with Arduino, ESP32, STM32, Raspberry Pi (with ADC), and other embedded development platforms.
