Detecting distances is a foundation of autonomous and guided robotics. It doesn't matter how smart your robot is if he keeps running into things!

We've got two different technologies of distance sensors; Infrared and Ultrasonic. Both have their advantages and we've got options for both.

Infrared

Infrared distances sensors are capable of precise and accurate distance measurements, however, they can be affected by certain lighting conditions.

  1. 3-Pin Female JST PH-Style Cable for Sharp Distance Sensors (30cm)
    Rating:
    100% of 100
    SKU: POLOLU-117 Brand: Pololu
    This 12-inch (30-cm) cable has 26 AWG wires and a 3-pin female JST PH-style connector that mates with the connector on 3-pin Sharp analog distance sensors. The other ends of the wires are unterminated; they can be cut to length to match your application. The wire color scheme matches the Sharp distance sensor pinout: red for power, black for ground, and white for signal.

Ultrasonic

Ultrasonic sensors are great in all kinds of lighting conditions, and you're measuring large, solid objects. Be sure to choose the correct beam pattern.
