Sharp Distance Sensor (20-150cm)






Using reflected IR light, measure the distance of an opaque object 20-150cm away. Requires an IR Distance Adapter to be used with Phidgets.






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

Based on "typical values" from Sharp, the formula to translate SensorValue into Distance (the formula is only valid for a SensorValue between 80 to 490) is:
Distance (cm) = 9462/(SensorValue - 16.92)

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, object alignment, ...). 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.

    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.



    This sensor connects to:

    The sensor plugs in the 1101 - IR Distance Adapter using the 30cm interface cable that comes with the 1101.
