Digital Infra-Red Rangefinding DIRRS+ Long Range


Price (CAD)
$19.50 ea.

This is the long-range version of the standard DIRRS+ serial-communicating IR distance sensor featuring Sharp technology.

Additional Information [Hide]

Much like the 39050 standard-range DIRRS+, this sensor uses the longer-range Sharp GP2Y0A02YK0F. When the Sharp sensors disappeared, this project was shelved, but with their re-introduction, we've dusted off and improved the code and adapted it to this longer-range version!

We've designed a daughterboard that takes the analog output of this great sensor, and makes it serial-compatible for most microcontroller uses, featuring:

Asynchronous Serial 8-bit output at 4800bps (Default mode)

  • Synchronous (clocked) serial 8-bit output (like original DIRRS & GP2D02)
  • Asynchronous serial 8-bit output in centimeters at 4800bps

The DIRRS+ does not require the special "JST-3 Sharp" connector and cable. Use a standard 0.100" header, or solder wires directly to the module PCB!

If you have a need to measure distances with the precision of the excellent Sharp GP2D12 quickly and simply, without having to burden your micro with more math, this is the unit for you! Here's more specifics:

  • Inexpensive (about 1/4 the price of Ultrasonics)
  • Simple to use
  • Small (4.5 x 2.2 x 1.9 cm)
  • Connects directly to any microcontroller I/O
  • Detection range: 20cm to 150cm (7.9"-59", almost 5 feet!)
  • Low microprocessor overhead (uses only 1 or 2 I/O line and a few lines of code)
  • Highly tolerant of ambient light and IR interference
  • Nearly immune to variations in object colour and reflectivity
  • Now an Open-Source Project
