QTI Line Sensor
(#550-27401)
Introduction
The Parallax QTI senor uses a QRD1114 infrared (IR) reflective sensor to determine
the reflectivity of the surface below it. When the QTI sensor is over a dark surface, the
reflectivity is very low; when the QTI is over a light surface, the reflectivity is very
high and will cause a different reading from the sensor.
Features
• Phototransistor Output
• No contact surface sensing
• Unfocused for sensing diffused surfaces
• Compact Package
• Daylight filter on sensor
