QRE1113 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for the QRE1113?
  The recommended PCB layout and land pattern for the QRE1113 can be found in the onsemi application note AND8325/D, which provides guidelines for optimal PCB design and layout to ensure reliable operation of the sensor.
• How do I adjust the sensitivity of the QRE1113?
  The sensitivity of the QRE1113 can be adjusted by modifying the value of the external resistor (R1) connected between the OUT pin and VCC. A lower value of R1 increases the sensitivity, while a higher value decreases it.
• What is the maximum distance the QRE1113 can detect an object?
  The maximum distance the QRE1113 can detect an object depends on the reflectivity of the object and the ambient light conditions. Typically, the sensor can detect objects up to 10 mm away, but this can vary depending on the specific application and environment.
• Can the QRE1113 be used in high-temperature applications?
  The QRE1113 is rated for operation up to 85°C, but it can be used in high-temperature applications with some limitations. However, the sensor's accuracy and reliability may be affected at temperatures above 85°C, and additional thermal management may be required.
• How do I interface the QRE1113 with a microcontroller?
  The QRE1113 can be interfaced with a microcontroller using a digital input pin. The sensor's OUT pin provides a digital output signal that can be connected directly to a microcontroller's digital input pin. The microcontroller can then read the sensor's output and respond accordingly.
