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). Our 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. See the Connection & Compatibility tab for details.

Sharp Sensor Adapter

This sensor connects directly to the Sharp sensor adapter so that it can be plugged into a Phiget InterfaceKit or Hub. They are connected using a custom cable that comes with the adapter.

Documents

If you are not getting good results with the standard formula, have a look at the product datasheet which has good notes on what can affect the sensor's performance

Accuracy

Connecting

All measurements are based on data provided by Sharp who used an r-27 calibration card, 90% reflectance. Based on our formula, we have calculated a minimum and maximum distance with the card at minimum and maximum distance.
