GP2Y0A02YK IR Proximity Sensor (20 to 150cm)

Part Number OPTDA-015000 Categories ,

The GP2Y0A02YK Sharp distance sensor is a great way to add obstacle avoidance or motion sensing to your robot or any other project. With a detection range of 20cm to 150cm and an analog voltage indicating the distance, this sensor is very easy to use. The sensor uses a 3pin JST (PH) female connectors.


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. The detection range of this version is approximately 20 to 150cm.
