## Description

A line follower sensor gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED. By measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it. Light-colored surfaces will reflect more light than dark surfaces, resulting in their appearing brighter to the sensor. This allows the sensor to detect a dark line on a pale surface, or a pale line on a dark surface. Note: This is the same line follower used with the XRP kits Beta & DIY Features: Operating Voltage: 3.3VDC Sensing Distance: 5-10mm Documents: QRE1113GR Datasheet
