The QTR-3A reflectance sensor is a type of optical sensor from Pololu that uses reflective infrared (IR) LED sources and analog phototransistors to measure distances from an object. It can detect objects from 0.2” to 3” away, with an accuracy of 0.25”. The QTR-3A has a 3.3V supply, a 0-3V logic output, and two power and logic connections that can be used to daisy chain multiple QTR-3A sensors. It is ideal for use in autonomous robots and other motion detection applications.
