Ultra-small obstacle detectors using the IS471 sensor. Assembly instructions are on BittyBot's website.

• Tiny single-sensor object-detector
• Only 0.40" x 0.35" x 0.14" thick
• Small enough to stick just about anywhere on your robot
• Short-range sensing of up to 4-6"
• "Objected detected" indicator LED eases debugging and adds to your robot's asthetics.
• Single high/low digital output easy to interface with most microcontrollers
• Digital output goes "low" when an object is in range
• Based on Sharp's popular IS471F sensor -- this sensor modulates the emitter IR LEDs and filters out return signals outside the modulation frequency for increased immunity to false triggering
• Available with a red, green, orange, or yellow indicator LED
• 5V operation
