Description

Phidgets 3522_0 Sharp Distance Sensor (20-150cm)

This popular sensor made by Sharp produces an analog output that varies from 2.5V at 20cm to 0.4V at 150cm.

Based on "typical values" from Sharp, the formula to translate output voltage ratio into Distance is:
Distance (cm) = 9.462/(VoltageRatio - 0.01692)

This sensor can find the distance to objects that present a very narrow edge such as a wall at a very sharp angle.

Note: The output of this sensor will vary from unit to unit, and based on the characteristics of the target (reflectance, size, direction of motion, and object alignment). The formula is based on the data provided by Sharp. If you find that you are not getting good results with the standard formulas, you may want to derive your own formula to better characterize your situation.

Connection
The sensor plugs in the 1101 - IR Distance Adapter.
