Specification
Brand : PARALLAX
BulletPoint : SYSTEM SENSOR LENSG COLORED LENS F/WALL GREEN
BulletPoint1 : The QTI Sensor is a close-proximity infrared emitter/receiver that is able to differentiate between a dark surface) with low IR reflectivity) and a light surface (with high IR reflectivity)
BulletPoint2 : Handy for line following, maze navigation, or sensing the outer rim of a SumoBot ring
BulletPoint3 : Wiring options allow it to be used digitally for fast black/white line following, or as an analog sensor to detect different shades of gray. A daylight filter is built into the sensor.
BulletPoint4 : What does QTI stand for? Q = Charge, T = Transfer, I = Infrared. When your microcontroller measures the time it takes for the QTI’s capacitor to decay, it’s measuring a rate of charge transfer through an infrared phototransistor. This rate indicates how much infrared is reflecting off a nearby surface.

ProductDescription :

The QTI Sensor is a close-proximity infrared emitter/receiver that is able to differentiate between a dark surface) with low IR reflectivity) and a light surface (with high IR reflectivity). These little sensors can be very handy for line following, maze navigation, or sensing the outer rim of a SumoBot ring. Wiring options allow it to be used digitally for fast black/white line following, or as an analog sensor to detect different shades of gray. A daylight filter is built into the sensor.

What does QTI stand for?

• Q = Charge
• T = Transfer
• I = Infrared

When your microcontroller measures the time it takes for the QTI’s capacitor to decay, it’s measuring a rate of charge transfer through an infrared phototransistor. This rate indicates how much infrared is reflecting off a nearby surface.

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)

Dimensions:

• PCB Length: 1”
• Overall Length: 1 ¼”
• PCB Width: 3/8”
• Thickness: 5/16”
