The Sharp GP2Y0A21YK0F is an infrared distance sensor that measures objects between roughly 10cm and 80cm and reports the reading as a simple analog voltage — no I2C or SPI bus setup required, just an ADC pin on the controller. That simplicity has made it a long-standing favourite for obstacle-avoidance and line-following robots.
Because it measures optically rather than through physical contact, it doesn't wear out the way a bump switch or contact sensor would, and works reliably across thousands of detection cycles. It reads directly into Arduino, Raspberry Pi, or ESP32 analog inputs, and the compact housing mounts easily on a robot chassis or automation fixture.
- 10-80cm infrared distance measurement
- Analog voltage output
- Non-contact, low mechanical wear
- Compatible with Arduino, Raspberry Pi, ESP32
A reliable choice for Indian robotics builders working on obstacle avoidance and collision detection.
