Product Description

The Sharp GP2Y0A21YK0F Distance Sensor is an infrared distance-measuring sensor designed to detect the distance between the sensor and an object within an approximate range of 10 cm to 80 cm. It uses infrared light and triangulation technology to provide an analog voltage output corresponding to the detected distance.

This sensor is suitable for Arduino projects, autonomous robots, obstacle-avoidance systems and electronic automation applications. Its analog output allows a compatible microcontroller to read sensor values and process them for distance estimation and object detection.

Unlike simple digital proximity sensors, the GP2Y0A21YK0F provides a varying analog output, making it useful for projects that need distance-related measurements. The relationship between output voltage and distance is nonlinear, so calibration or a suitable conversion method may be required for accurate readings.
