Each module uses a QRD1114 IR reflection module that charges up & discharge a tiny capacitor. By either monitoring the reflection level directly (analog), or the time it takes to change logic state (digital), you can detect a line on a surface. Here’s Parallax’s text: 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. The QTI Sensors were originally meant to sense the outer rim of a SumoBot® ring; however these little line sensors can be very handy for other applications, including line following and maze navigation. Features: Capable of analog or digital outputs No contact surface sensing Unfocused for sensing diffused surfaces Daylight filter on sensor Easy to interface with any Parallax microcontroller Specifications: Power requirements: 5 VDC Communication: Analog output of capacitor decay time depending on level of infrared reflectivity Dimensions: 1.25 x 0.37 in (31.7 x 9.4 mm) Operating temp range: -40 to +185 °F (-40 to +85 °C) Resources QTI Sensor ManualDocumentationQTI Line Follower ManualDocumentation More Info Weight 0.003 kg Dimensions 5 × 5 × 1 cm Reviews There are no reviews yet.Only logged in customers who have purchased this product may leave a review.
