The Sharp Distance Sensor (20-150cm) utilizes reflected infrared light to measure the distance of opaque objects within a range of 20 to 150 centimeters. It generates an analog output that varies with distance, providing a voltage from 2.5V at 20cm to 0.4V at 150cm. This sensor is capable of detecting objects with narrow edges, such as walls at sharp angles, and connects to the Phidgets 1011 IR Distance Adapter. The output may vary depending on the target's reflectance, size, motion direction, and alignment.
