QRE1113 IR LED Infrared Reflection Sensor Generic Capacitor 3.3-5V

Description

Product Overview

The QRE1113 IR LED Infrared Reflection Sensor is a compact, high‑performance module designed for reliable proximity detection in a wide range of industrial and hobbyist applications. Built around a proven infrared LED and phototransistor pair, the sensor emits a focused beam of infrared light and measures the amount of light reflected back from nearby objects. The integrated capacitor discharge circuit stabilizes the output signal, reducing noise and ensuring consistent performance across temperature variations and power fluctuations.

Key specifications include a supply voltage range of 3.3 V to 5 V DC, a low power consumption profile, and a board layout that accommodates easy soldering onto prototype or production PCBs. The module’s footprint measures just a few millimetres on each side, making it ideal for space‑constrained designs while still providing a robust detection range of up to 10 mm for most reflective surfaces.

Usage

This sensor excels in environments where precise, short‑range detection is required. Typical use cases include line‑following robots, obstacle avoidance systems, conveyor belt item counting, safety interlocks, and touchless user interfaces. Because the sensor operates on low voltage, it can be powered directly from microcontroller boards such as Arduino, ESP32, or Raspberry Pi Pico without the need for additional voltage regulation.

In robotics, the QRE1113 provides fast response times that enable smooth navigation around tight corners and dynamic obstacles. In industrial automation, it can be employed to verify the presence of components on assembly lines, trigger alarms when objects are out of position, or control pneumatic valves based on proximity. The sensor’s durability also makes it suitable for outdoor installations where dust, humidity, and temperature changes are common, as the infrared wavelength is less affected by ambient lighting conditions.

FAQ

What is the detection range of the QRE1113 sensor?

The sensor reliably detects reflective objects up to approximately 10 mm away. The exact range can vary based on surface reflectivity and ambient lighting conditions.

Can the sensor be used with a 5 V power supply?

Yes, the QRE1113 operates safely within a 3.3 V to 5 V DC supply range, making it compatible with both low‑voltage and standard 5 V microcontroller boards.

Is additional circuitry required for signal conditioning?

For most applications the built‑in capacitor discharge provides sufficient signal stability. However, if you need amplified output or specific filtering, external op‑amp circuits can be added according to the datasheet recommendations.

How does the sensor perform in bright ambient light?

The infrared wavelength used by the sensor is less affected by visible light, allowing reliable operation even under strong indoor lighting. For outdoor or highly reflective environments, shielding the sensor or using a modulated signal can improve immunity to interference.
