Sharp Distance Sensor 2Y0A21 (10-80cm) info

About the Product

The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. Sharp Distance Sensor 2Y0A21 (10-80cm) 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. The detection range of Sharp Distance Sensor 2Y0A21 (10-80cm) is approximately 10 cm to 80 cm.
