Description

This popular sensor made by Sharp produces an analog output that varies from 3.1V at 4cm to 0.3V at 30cm.

Based on “typical values” from Sharp, the formula to translate output voltage ratio into distance is:

Distance (cm) = 2.076/(VoltageRatio – 0.011)

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.

The Sharp Distance Sensor 4-30cm is a reliable infrared distance sensor designed for Arduino projects, robotics systems, automation applications, and embedded electronics development. This sensor measures object distance using infrared technology and provides accurate readings for short-range sensing applications.

Because distance sensing is important in robotics and obstacle detection systems, this sensor helps developers build responsive automation and navigation projects. In addition, the compact design makes installation easier in prototype systems and embedded hardware.

Many students, makers, and engineers use this sensor for robotics navigation, smart sensing systems, and educational electronics projects. You can also combine it with Arduino UNO R3 for accurate distance measurement applications.
