Description
This version of the QRE1113 breakout board has an easy-to-use analogue output that varies depending on the amount of IR light reflected to the sensor. This tiny board is perfect for line sensor applications and can be used in both 3.3V and 5V systems.
The QRE1113 IR reflection sensor of the board consists of two parts - an IR emitting LED and an IR-sensitive photo transistor. When you supply power to the VCC and GND pins, the IR LED inside the sensor lights up. A 100? Resistor is integrated and connected in series with the LED to limit the current. a 10k? Resistor draws the output pin up, but when the light of the LED is reflected back onto the photo transistor, the output starts to go down. The more IR light is detected by the photo transistor, the lower the output voltage of the breakout board.
These sensors are often used in sequence robots - white surfaces reflect much more light than black, so when directed to a white surface, the voltage output is lower than that on a black surface. The board also has a single mounting hole if you want to screw the board onto something.
