Digital Infra-Red Rangefinding (DIRRS+)

HVW takes a Sharp GP2D12 sensor, and adds their own brains to it. Not only does it duplicate exactly what the original GP2D12 offered, it one-ups it by talking several ways to your microcontroller:

• 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 1.5 x 2.3 cm)
• Connects directly to any microcontroller I/O
• Detection range: 10 cm to 80 cm (4" to 31")
• 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 reflectivit
