Sharp GP2Y0A21YK0F Analog Distance Sensor 10–80 cm

The Sharp GP2Y0A21YK0F Analog Distance Sensor is a compact module designed for detecting objects within a 10–80 cm range. It outputs an analog voltage proportional to the distance, allowing easy integration with Arduino, Raspberry Pi, and other microcontrollers. Operating at 4.5–5.5 V with a typical current of 30 mA, the sensor supports obstacle avoidance, motion detection, and interactive robotics applications. With a sampling rate of 26 Hz and a voltage differential of 1.9 V, it provides reliable and continuous distance measurement for real-time control systems. Its small form factor facilitates integration in both prototype and finished projects.
