Sharp IR Proximity (GP2Y0A21YK0F) is an IR sensor useing infrared wave to measure distance
Optical Flow image Sensor (Position Measuring By Image Processing) 3 Axis Gyroscope It is suitable for detectingIntroduction: This sensor is based on the idea of optical mouse (image sensor). It senses the image (camera sensor) of a surface or an object by taking very large number of images (frames) in short time. Using build in image processing algorithm, then the displacement of the object can be defined. Connections: How it works The mouse sensor returns the average movement (in the x and y directions) of surface features that it sees. A single pixel move
