The GP2Y0A51SK0F is the shortest-range Sharp analog distance sensor we carry, featuring a detection range of 0.8″ to 6″ (2 cm to 15 cm). The shorter range gives you higher resolution measurements, and the low minimum detection distance makes this sensor great for detecting very close objects. The distance is indicated by an analog voltage, making this sensor very easy to use.
The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. This IR sensor is more economical than sonar rangefinders, yet it provides much better performance than other IR alternatives. Interfacing to most microcontrollers is straightforward: the single analog output can be connected to an analog-to-digital converter for taking distance measurements, or the output can be connected to a comparator for threshold detection, making this an adjustable-threshold alternative to digital Sharp sensors. The detection range of this version is approximately 2 cm to 15 cm (0.8″ to 6″).
