QTI Sensor

£11.56
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

Key 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)
