QTI Sensor (Line Follower)

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 microcontroller Key Specifications: Power requirements: 5 VDC Communication: Analog output of capacitor decay time depending on level of infrared reflectivity Operating temp range: -40 to +185 °F (-40 to +85 °C) • Dimensions: 1.25 x 0.37 in (31.7 x 9.4 mm) Works with: (Available for Purchase Separately) • Arduino Uno add-on Kit (EMC-GEO1-001)
