Reflectance sensor QTR-L-1A, analog (x2), Pololu 2454

The sensor consists of an IR LED and a receiver in the form of a phototransistor. In addition to these two basic elements, in the circuit are: resistor limiting the transmitting LED's current 220 Ω and the pulling-up resistor, output of the phototransistor collector for supply voltage with the value of 20 kΩ. The output is an analog voltage that depends on the color of the surface.

Specification:

• The supply voltage: 5 V
• The average current consumption: 17 mA
• Recommended measuring range: 3 mm - 6 mm
• Maximum measuring range: 25 mm
• Output: voltage-analog signal (0 V up to the value of the supply voltage)
• Dimensions : 7.6 x 8.9 x 3.1 mm (without connectors)
• Weight: 0.2 g (without connectors)
