Long range Sharp IR sensors are used to measure the range to distant objects at ranges up to 150 cm. These work great on robots for obstacle detection and navigation and can be mounted on servos for radar-like object detection.
Each sensor also comes with wires.
Formulas for Converting Voltage to Range
Try some of these algorithms to convert the measured analog voltage to range in centimeters on a device like an BoardX or Arduino:
Arduino Library: https://code.google.com/p/gp2y0a21yk-library/
From Voltage to Distance in Centimeters:
range (cm) = 306.439 + voltage * (-512.611 + voltage * (382.268 + voltage * (-129.893 + voltage * 16.2537)))
If you need extra analog to digital conversion channels to read several of these, we'd highly recommend checking out our ADC-X Analog to Digital Converter Add-on. It gives you 8 channels of analog data via I2C with 8bits of quick precision.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
Our mission is to design electronics that are easy to use, widely adaptable and suitable for students, hobbyists and professionals. Each product was inspired by our experiences as engineering students and our dissatisfaction with what the market had to offer. After studying the weaknesses of competing products, we made those the focal point of our designs.
We're proud to say that all of our boards are designed, tested and in most cases built in the USA.
